Visual MINTEQ ver. 3.0
Visual MINTEQ is a freeware chemical equilibrium model for the calculation of metal speciation, solubility equilibria, sorption etc. for natural waters. It combines state-of-the-art descriptions of sorption and complexation reactions with easy-to-use menus and options for importing and exporting data from/to Excel. Chemical equilibrium modelling has never been easier!
Visual MINTEQ will run on most Windows platforms and relies on .NET Framework. For more details, see here.
Easy yet powerful
In 2009 and 2010 Visual MINTEQ was the second-most used chemical equilibrium software application among researchers publishing in Elsevier journals. Probably this is because it is easy to learn, yet powerful, for many kinds of chemical equilibrium problems.
