![]() ![]() The program aqion, that relies on the numerical solver of PhreeqC, belongs to the LMA category as well. The LMA approach is common, and available in many computer programs, such as PhreeqC, Minteq 2, Wateq4f 3, EQ3/6 4, Chess/JChess 5, The Geochemist’s Workbench 6 and others. models based on GEM – Gibbs Energy Minimization.models based on LMA – Law of Mass Action. ![]() In all calculations partial/local equilibrium is assumed, therefore they are also termed “thermodynamic equilibrium models” (in contrast to kinetic models).ĭespite the huge diversity we encounter in hydro/geochemistry models and software today, all these approaches fall into two major categories: Temperature T, pressure P, and total concentrations of elements 1Ĭoncentrations c i (or molar amounts n i) of chemical species in aqueous and other phases in equilibrium state From a thermodynamic point of view they solve the following task: Given: In the last decades, a large variety of models and computer programs has been developed for applications in hydro- and geochemistry.
