| Abstract: | The chemical model of aqueous systems are becoming a valuable tool for geochemist ininterpretation of equilibrium and kinetic phenomena of natural water systems. In this pa-per,the historical aspects and features,including the mathematical formalism and the ther-modynamic formalism,of chemical equilibrium computation were described.The chemicalmodels used in geochemical research could be seperated into several series and were brieflyintroduced.In the past decade,few new model codes appeared and great effort was under-way to improve and qualify existing models.An obvious feature of the new model is thatthese model can provide several methods to calculate the activity coefficients of aqueous so-lution from dilution to high concentration. The new concern of chemical modeling as fol-lows:model sensitivity analysis,thermodynamic and kinetic data advancements,organiccompounds,and coupling of hydrology and chemistry. |
