Abstract: A new method called differential reciprocal oscillographic ehronopoientiometric titration is presented,it maked use of appearance or disappearance of a peak of depolarizer on differential reciprocal oseillogram to indicate the end point of titration.This method was applied to the titration of Pb2+,Cd2+,Ni2+,Co2+,Zn2+,Ga3+ and Cu2+ by EDTA or EGTA.The end point of titration is very easy to be observed

Key words: Differential reciprocal oseillographic chronopotentiometric titration, Oscillographic atration, Depolarizer
