Electrodeposition of a tellurium-iodine compound

Forming more stable tellurium in iodide solution was investigated. Solutions with a large excess of iodide ions were prepared and radiotracers measured the current yields of tellurium. A platinum sheet was used as cathode, a tellurium rod was the anode, and a saturated silver-silver chloride electrode was the reference electrode. Electrodeposition and polarization measurements were conducted by a potentiostat. Polarization curves were obtained. Iodine 125 and tellurium 123m were used in the radiochemical analysis of the deposition yield and rate. Radioactivity measurements were made with a Ge(Li) detector
