【 摘 要 】

The electrochemical behavior of N-nitrosothiazolidinecarboxylic acid (NTAC) on gold and hanging mercury electrodes, using the cyclicand square wave voltammetries, was studied. Whereas NTAC suffer reduction ina single step on the mercury electrode, two peaks appears on the cyclic voltammogramson the gold electrode, one anodic peak overlaying the gold oxide process at1.2 V and one cathodic peak at -0.41 V vs Ag/AgCl, KCl 3.0 mol L-1.The cathodic peak depends on the previous oxidation of NTAC at the electrodesurface, presents irreversible and adsorption controlled characteristics andit is suitable for quantitative purposes.
