A new method called differential reciprocal oscillographic chronopotentiometrictitration is presented.It makes use of appearance or disappearance of a peak of depolarizer ondifferential reciprocal oscillogram indicating the end point of titration.This method was appliedto titration of Pb2+, Cd2+, Ni2+, Co3+, Zn2+, Ga3+ and Cu2+by EDTA or EGTA.The end point oftitration is very easy to observe and the sensibility of the method is higher than that ofdiffcrcntial oscillographic chronopotcntiometric titration
