Volumetric Determination of Tellurium in Commercial Metallic Tellurium and Tellurium-enriched Material

Determination of high-content tellurium in commercial metallic tellurium and low-content tellurium in tellurium-enriched material was carried out by volumetric titration with potassium dichromate.The above method is suitable for tellurium determination of the materials containing 1%～99.5%tellurium.
