Aquawolfe Posted June 9, 2012 Share Posted June 9, 2012 Hi. I'm trying to model pyrite oxidation in a batch reactor (Liu et al 2008). Both pH and the concentration of dissolved oxygen in the system is held constant (at 3 and 9-12 ppm, respectively). pH is maintained by through discrete additions of HCl or NaOH The concentration of dissolved oxygen was maintained by controlling the oxygen partial pressure in the reactor headspace When I try to fix O2 in the Reactants window, I get a convergence error. As soon as I "unfix the O2", the program is able to arrive at a solution. I'm new to GWB, so any advice is greatly appreciated! Many thanks, in advance, for your time!
