✦ Synopsis

According to a theoretical analysis in which the anodic stripping of tellurium in tnethylene chloride, containing chloride ions, was treated as an electrochemical adsorption reaction the second step of the oxidation reaction, which corresponds to the first anodic wave, is rate determining and is preceded by a quasi-reversible reaction, while the oxidation reaction which corresponds to the second anodic wave is irreversible, with the first step beingrate determining. It is shown that the first anodic stripping waveis due to the oxidation of tellurium atoms which are on the surface of the tellurium electrode, while the second wave is due to the oxidation of telluriumatoms. which are situated on inner surfaces of themetal before the first wave is recorded.

The potential of tellurium anodes has been measured as a function of current density in 0.01-3 N NaOH at 30Β°C. The results indicate the oxidation of tellurium into tellurous acid. The initial discharge of hydroxyl ions governs the overall reaction rate within the concentration range 0.01-l N. In con
