Conclusions
An accelerated method is proposed for the analysis of copper tellurides without prior separation of the elements: Copper is determined complexometrically in the presence of tellurium, when the amount of the latter is from 40 to 60%, while tellurium is determined by a bichromate method in the presence of copper, using a separate batch. The duration of the copper determination is 1.5 h and that of the tellurium determination, 4 h.
The accuracy of the copper and tellurium determinations is ±0.02 and ±0.05%, respectively (at 0.95 probability confidence).
