CuSO4·5H2O, CaO or NaOH can be used to adjust PH. The equation is: S2O52- + 2CN- + 2O2 + H2O Cu2+ 2CNO-+2H+ + 2SO42- èCNO-+2H2O èHCO3- + NH3 The reaction normally need the PH around 7-10 (8-9.5 is the best) The sequence of oxidization is: CN->Zn(CN)42->Fe(CN)34->Ni(CN)42->Cu(CN)42->SCN- The CN- will be oxidized and the heavy metals will be precipitated as XFe(CN)6, X(O
