Substitution complexometric determination of cadmium in the presence of zinc in homogeneous water-organic solvent medium.
A method for substitution complexometric determination of cadmium is based on the decomposition of the Cd-EDTA complex by the combined action of ethylxanthate and zinc. The reaction is performed in a slightly acid homogeneous water-organic solvent medium in which the cadmium ethylxanthate complex is stable and soluble.
