mmontecinos1 Posted April 17, 2018 Share Posted April 17, 2018 Hello everyone, I am trying to reproduce the surface precipitation model of Cu in HFO y HAO developed by Karthikeyan and Elliott (1999) (Surface Complexation Modeling of Copper Sorption by Hydrous Oxides of Iron and Aluminum, Journal of Colloid and Interface Science 220, 88–95 (1999). I would like to edit FeOH.dat sorption file to include equations  to  considered by the authors. However, I am not sure how due to these equations consider both sorbed and precipitated species To include eqs.  and  I was thinking of include the following species: >(s)FeOHCu(OH)2H+ charge= 1.0 mole wt.= 171.4228 4 species in reaction 1.000 >(s)FeOH -1.000 H+ 1.000 Cu++ 2.000 H2O log K= -0.7500 dlogK/dT= 0.0000 >(w)FeOHCu(OH)2H+ charge= 1.0 mole wt.= 171.4228 4 species in reaction 1.000 >(w)FeOH -1.000 H+ 1.000 Cu++ 2.000 H2O log K= -0.7500 dlogK/dT= 0.0000 but I am not sure if this is a proper way to represent this model of surface precipitation. Regarding to eq.  and , I don’t know how to include it, due to these equations represent the change in Ksp precipitation due to HFO adsorption. I would appreciate any recommendationBest regards, Mauricio Montecinos Quote Link to comment Share on other sites More sharing options...
