EDTA titration of tellurium, based on the formation of copper(I) telluride.
An indirect EDTA titrimetric method is described for the determination of tellurium in thermoelectric materials and synthetic mixtures. Stoichiometric copper(I) telluride is precipitated from a hot acidic solution in the presence of excess of copper(II) chloride and sodium hypophosphite. The method is accurate (mean relative error 0.5%) and selective.
