Snapshot of the amended zirconium datasheet.4.3.4 Simple Functions Spreadsheet ValidationIn order to verify the implementation of the modifications in the Simple FunctionsSpreadsheet tool, solubility limits as well as Saturation Index calculated with the toolhave been compared with results obtained for the same calculations performed withthe geochemical code PhreeqC (Parkhurst and Appelo, 2013). Results of thecomparison are shown in Figure 4-31, Figure 4-32, Figure 4-33, and Figure 4-34. Thegood agreement between the results obtained using the Simple Functions spreadsheettool and the more sophisticated PhreeqC code is remarkable.52
