An electrochemical study was made of the anodic behavior of sodium diethyldithiocarbamate (DEDTC) using a boron-doped diamond electrode (BDDE) in sodium sulfate supporting electrolyte. This paper presents a new alternative for the electroanalytical determination of DEDTC in protic media, using cyclic voltammetry or chronoamperometry. Linear plots of current vs. concentration correlated with anodic stepwise oxidation were obtained in delimited potential ranges with very good correlation coefficients.
