1 Introduction
This open file report aims to present an intercomparison of thermodynamic databases by means of Eh-
pH diagrams, which are practical and useful for understanding geochemical behavior of elements. An
Eh-pH diagram depicts the dominant aqueous species and stable solid phases on a plane defined by the
Eh and pH axes. In an Eh-pH diagram, the solid stability area is related to the saturation condition,
and dominant aqueous species give us fundamental information on sorption and colloid phenomena as
well as surface characteristics of materials. Eh-pH diagrams are thus essential to understanding solute
and radionuclide transport in groundwater.
The most well-known studies on comprehensive Eh-pH diagrams are those of Pourbaix (1966) and
Brookins (1988). The former discussed corrosion, passivation and immunity of materials, while the
latter reported geochemical aspects of the geological disposal of radioactive wastes. These studies
have been followed by many thermodynamic databases.
With the ever increasing CPU power of computers, we have started utilizing geochemical codes for
calculation of complex chemical reactions. Thus, thermodynamic databases have gained importance
from a practical perspective.
Certain geochemical codes enable us to obtain Eh-pH diagrams easily and quickly. With the aid of
software, Eh-pH diagrams can provide us with good insight into the state of the art in thermodynamic
databases and the differences between them.
It should be noted that this open file report presents the Eh-pH diagrams calculated from databases
as is , without any critical comments. It should also be noted that Eh-pH diagrams represent
one aspect of thermodynamic databases and databases are often updated, thus this report is only a
snapshot of the present. I would be very pleased if this open file report proves useful in helping the
readers use thermodynamic databases.
2 Databases
Let us compare the seven databases listed below. The first database is generic and popular in inorganic
chemical engineering. The second and third are generic and popular in geochemistry. The fourth and
fifth serve for safety assessment of geological disposal of radioactive wastes, but their coverage of
chemical species is sufficiently wide to be suitable for generic use. The sixth and seventh databases
mainly cover data on radioactive elements, with incomplete data on other elements. The current report
presents only Eh-pH diagrams of radioactive elements included in the sixth and seventh databases.

3 Method for constructing Eh-pH diagrams
The present report includes Eh-pH diagrams for the X-H-O system, where X = the symbol of an
element like Na, K. This is the most important system for the chemical description of elements in
groundwater. To understand the geochemical system of the natural barrier, we took account of not
only radioactive elements, but also other elements included in the databases. However, OECD-NEA
databases were excluded due to their restricted coverage of the data on non-radioactive elements.
Total concentration of elements is 10-10 mole/kg for all diagrams. Such a low concentration enables
us to safely assume the activity coefficient to be unity and impedes precipitation of the solid phases
which hide the area of dominant aqueous species in the Eh-pH diagram.
To avoid unexpected errors during data conversion, databases bundled with commercially available
software and databases distributed in the specific format of the software are handled with appropriate
software to draw Eh-pH diagrams. Databases of the former type are FACT and LLNL, bundled
with FACTSAGE and GWB, respectively. The database of the latter type is JNC-TDB, which is
distributed in three formats: EQ3/6, PHREEQC, and GWB. In this report, a version in the GWB
format was used. For the other databases, namely SUPCRT, HATCHES, OECD-NEA, and OECD-
NEAupdate, the in-house software FLASK-AQ and its companion software EhpHdraw were used to
draw the Eh-pH diagrams.
The drawing method for Eh-pH diagrams is well explained in many textbooks of chemical ther-
modynamics (e.g. Garrels and Christ, 1965). The algorithm for drawing Eh-pH diagrams is not
documented in the commercially available software FACTSAGE and GWB.
FLASK-AQ calculates concentration of aqueous species in equilibrium and moles of stable solid (if
present) on grids into which Eh and pH are divided, the Eh in 0.005 V increments from -0.8 V to 1.2
V, the pH in increments of 0.04 from 0 to 14, and outputs the dominant species and the stable solid.
Companion program EhpHdraw draws Eh-pH diagrams using the output of FLASK-AQ. This method
resembles that reported by Anderko et al. (1997). Unfortunately, since Anderko et al. (1997) did
not describe their method in detail, I cannot compare the two methods. The accuracy of the present
method for drawing boundaries between dominant species or solids depends on the grid size, which
inevitably leads to errors as large as 0.0025 V and 0.02 units for Eh and pH, respectively. The following
subsections describe the method for drawing Eh-pH diagrams for each database. The database name
and software name (both in abbreviation) are concatenated by a slash (Figure 1).

3.1 FACT/FACTSAGE
Eh-pH diagrams are created with EpH of FACTSAGE and saved as a BMP file. This file is used as a
template for the line drawing software Illustrator (Adobe Illustrator) and resized to the common axial
length.
3.2 SUPCRT/FLASK-AQ
The FLASK-AQ input file was created from the output of SUPCRT92. FLASK-AQ creates an inter-
mediate file from which EhpHdraw draws an Eh-pH diagram on the X window system. This Eh-pH
diagram is captured to an X window dump file using xwd , and then converted to a BMP file with Im-
ageMagic. This BMP file is used as a template for Illustrator and resized to the common axial length.
An enormous amount of organic species in this database are expressed stoichiometrically in terms of
C, H, and O as basis species. Calculations reveal that almost all organic species are decomposed under
the stability field of water under ambient conditions.
3.3 LLNL/GWB
The Eh-pH diagram is created with Act2 of GWB and is saved as a PostScript file. This file is converted
to a PDF (portable document file) file with Adobe Acrobat Distiller and opened with Illustrator and
resized to the common axial length.
3.4 JNC-TDB/GWB
The Eh-pH diagram is created with Act2 of GWB and saved as a PostScript file. This file is converted
to a PDF file with Adobe Acrobat Distiller and opened with Illustrator and resized to the common
axial length. All diagrams were first created using 011213g0, and S and U data were updated with
011213g2, fixing the erroneous S and U data in the previous version. Visual inspection confirms that
all diagrams other than those of S and U are identical between 011213g0 and 011213g2, i.e., that all
diagrams from 011213g0 remained unchanged except those of S and U.
3.5 HATCHES/FLASK-AQ
The files of EQ3/6 format data bundled with HATCHES are combined into a single file in which some
aux species with the improper keyword basis were corrected. This file is converted to a FLASK-AQ
input file using the in-house software AIST TDBCONVERT. FLASK-AQ creates the intermediate file
from which EhpHdraw draws an Eh-pH diagram on the X window system. This diagram is captured
to an X window dump file using xwd , and then converted to a BMP file with ImageMagic. This
BMP file is used as a template for Illustrator and resized to the common axial length.
Organic species are expressed stoichiometrically in terms of the ligand species. Note that this
method differs from the case of SUPCRT/FLASK-AQ. However, this difference does not affect the
Eh-pH diagrams because ligand species are not included in the X-H-O system.
3.6 OECD/NEA
The tables listing the Standard Gibbs Free Energy of formation for the elements in the OECD-NEA
Chemical Thermodynamics vol. 1-4 are entered into a spread sheet and saved as a text file and
converted into FLASK-AQ format using in-house software. FLASK-AQ creates the intermediate file
from which EhpHdraw draws the Eh-pH diagram in the X window system. This Eh-pH diagram is
captured to an X window dump file using xwd , and then converted into a BMP file with ImageMagic.
This BMP file is used as a template for Illustrator and resized to the common axial length.

3.7 OECD-NEA update
The source database of OECD-NEA Chemical Thermodynamics vol. 5 was processed in the same way
as OECD/NEA described above.
4 Explanation of the diagrams and tables
Tables and diagrams are presented in alphabetical order of the chemical symbol of the element. The
tables precede the diagrams for each element. The top row of the table contains the database name.
The database name and software name (both abbreviation) concatenated with a slash ( / ) are found
above the diagram next to the chemical symbol of the element (Figure 2). A blank column in the table
and NODATA in the diagram mean either no data for elements or no data for aqueous species of
elements . The expression of the chemical formula used in the table and diagram is the same as in the
source database, namely as is . This was done to abide by the concept of the database compilers.
Consequently, it should be noted that the expression for hydration and the solid phase differs between
the databases. The expression for the charge has the same style throughout, while the expression for
the solid has many variants: am denotes amorphous, c or cr denotes crystalline, s or no index
indicates no discrimination for amorphous or crystalline. Some solid phases are labeled with mineral
names. FACT database uses s1 , s2 , s3 notation for polymorph phases, and the present report
uses the same notation for the diagram from FACT/FACTSAGE. The names of solid phases in the
table and diagram are typed in bold face. The area between the two diagonal lines from the upper left
to the lower right in the diagram indicates the stability field of water at 298.15 K and 105 Pa. The
tables list chemical species whose Eh-pH diagrams can be drawn individually for the database. Certain
chemical species do not appear in the diagram because they are unstable or no data is available on
them. Thus, it is important to consult the table carefully when using the diagrams.

5 Reliability and uncertainty
The reliability and uncertainty of diagrams depend on the following three factors. 1) Reliability of
and error in the data in the databases, 2) Uncertainty of the software used for Eh-pH calculation, 3)
Fidelity of the drawing. The error is not mentioned in the databases except the OECD-NEA Chemical
Thermodynamics Series. The uncertainty in the commercial softwares for drawing Eh-pH diagrams
is not described. The uncertainty in FLASK-AQ depends on grid size, as already mentioned. The
fidelity of the drawing is confirmed within the grid size of FLASK-AQ by visual inspection. Thus,
the overall error excluding errors stemming from the databases and commercial softwares are within
ą0.0025 V for Eh and ą0.02 units for pH.
6 Description of the softwares and their execution environments
The software used for Eh-pH calculation are GTT-Technologies FactSage 5.2 and Illinois University
Geochemist s Workbench 4.0 and the in-house software AIST FLASK-AQ 1.1. FactSage 5.2 and Geo-
chemist s Workbench 4.0 are executed under a Microsoft Windows 2000 Server on a Dell PowerEdge
2600 (Xeon 2.4GHz x2 SMP with 4GB memory). FLASK-AQ 1.1 is executed under SuSE Linux 7.3
(kernel 2.4.20) on HIT PC (Pentium4 2.8 GHz with 1GB memory). FLASK-AQ 1.1 was compiled with
Intel C++ 7.0 compiler and executed with batch scheduling software LSF 4.2. To obtain the Eh-pH
diagrams from the intermediate file of FLASK-AQ 1.1, the in-house software AIST EhpHdraw was
used. ZZ-HATCHES-15 data was converted into the FLASK-AQ format using the in-house software
AIST TDBCONVERT coded by Nihon sgi. All in-house software of AIST will be released to the
general public in the future.
To obtain snapshots of the Eh-pH diagram drawn by EhpHdraw, the X Window dump software
xwd was used. To convert from the XWD to BMP format, convert of ImageMagic was used.
These procedures were carried out under Red Hat Linux 9 or Fedra Core 2 on an IA32 PC.
Conversion from the PostScript file to the PDF file was performed with Adobe Acrobat Distiller
4.0. Trace of the template image, resizing and cosmetics of the diagrams, and outputting to the EPS
file were performed using Adobe Illustrator 8.0 under Microsoft Windows 2000 Professional on an
IA32 PC.
The lists of chemical species in the tables were created with Sun StarSuite 6.0 and saved as
PostScript files and converted into EPS files with ps2epsi under Fedra Core 2 on an IA32 PC. The
final draft of this report was printed out using LaTeX and dvips , on a Laser printer under Fedra
11
Core 2 on an IA32 PC(Table 1).
