Kaizen Posted May 20, 2013 Share Posted May 20, 2013 I have an acidic (pH 2) highly saline oxygenated solution based on seawater with a range of other metal salts added. In actual experiments we also add FeSO4. We then add H2O2 to oxidise the Fe2+ to Fe3+. In Spec8 this creates a charge imbalance as there are additional anions required to balance the additional Fe charge. There is little change in pH. In Spec8 the predominant Fe species remains as Fe2+ where it should be Fe3+ after H2O2 addition. How do I charge balance in this case and maintain Fe3+ as the predominant Fe species? Any tips appreciated. Thank you. Quote Link to comment Share on other sites More sharing options...
Brian Farrell Posted May 21, 2013 Share Posted May 21, 2013 Hi, Do you have a script that you can post? And a thermo database with H2O2 added? Thanks, Brian Farrell Aqueous Solutions LLC Quote Link to comment Share on other sites More sharing options...
