Abstract: Anew method known as oscillographic voltammetric titration on Anti lgif-Ecurves is presented, and circuit of oscillographic voltammetric titration was improved by this method.In this way, Ga3+, Cd2+, Zn2+, Ni2+, Co2+ were directly titrated with EDTAor EGTA.The experiment results show that the sensibility and accuracy of this method are better than those of oscillographic voltammetric titration on if-Ecurves.

Key words: Oscillographic voltammetric titration, Double electrolyzer, Anti lgil1-R curve
