文摘A new method called differential reciprocal oscillographic chronopotentiometric titration is presented.It makes use of appearance or disappearance of a peak of depolarizer on differential reciprocal oscillogram indicating the end point of titration.This method was applied to titration of Pb^(2+),Cd^(2+),Ni^(2+),Co^(3+),Zn^(2+),Ga^(3+) and Cu^(2+)by EDTA or EGTA.The end point of titration is very easy to observe and the sensibility of the method is higher than that of diffcrcntial oscillographic chronopotcntiometric titration.
