Abstract
A mathematical expression is derived for the radiocomplexometric determination of a mixture of two metals with one ligand, using an anion exchanger in the solution as a phase separating system. An expression is also given for the complexometric titration of a metal, when formation of acidic or basic complexes is taken into account. In the experimental part titration procedures are proposed for determinations of nickel, copper and iron, using65Zn as indicator. The formation of the acidic complex, ZnHY, does affect the radiometric titration curve of zinc with EDTA.
