Stripping Voltammetry of Tellurium (IV) In 0.1M HC10 4 at Rotating Gold Disk Electrodes.
The stripping voltammetry of Tellurium (IV) in 0.1M HC10, using gold electrodes is described. Detection limits for solid gold, in situ gold-plated and externally gold-plated rotating glassy carbon disk electrodes are presented. No significant increase in sensitivity is reported for the use of solid …
