Dear Dr. David Parkhurst
I want use the PHREEQC to forward modelling the oxidation of arsenopyrite by Fe+3, to simulate bacterial action in oxidation process, with this equation: FeAsS + 13 Fe+3 + 8H2O = 14Fe+2 + HSO4-2 + SO4-2 + 15H+, but I don´t know how introduce the Fe3+ in the WATEQ4Fdatabase file, without cause any trouble in the program calculations, to use it in the REACTION block, could you have some sugestion to solve this problem?
Thanks in for your attention
