Abstract

A method was described for the eliminating the ammonium oxalate interference of Ag+ and Hg2+ with the NallylN′(sodium pphenylsulfonate) thiourea(NaNTU) in the identification of Ca2+ using (NH4)2C2O4. Compared to the traditional methods, this method is easy,simple and good effects.
