title: EDTA titration of tellurium, based on the formation of copper(I) telluride.
abstract: 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.
