The Spectrographic Determination of Traces of Tellurium

Volume 25, Number 4 (Aug. 1971) Page 493-496

Marks, J.; Cone, R.; Leao, E.


A spectrographic method for the determination of as little as 0.3 μg tellurium in nickel-base alloys has been developed. The method utilizes a preliminary separation and concentration of tellurium by precipitation of the metal with stannous chloride. The precipitate is then filtered and the filter paper ashed in the spectrographic electrode. Tellurium is measured by a dc arc technique.
