Abstract: In this paper the condition and composition of the ternary complex for determination of cadmium with Cd-methyl thymol blue-cetyl trimethyl ammonium bromide have been put forward.This method is characterized by high sensibility and good sebectivity, and especially by stable colour with rapid reaction.We have, moreover, proposed a new method tb determine cadmium in air, without separating Cd from its accompanying elements, with ammonium fluoride and phenanthroline as masking reagents of Ni, Co, Mg cations.
