Electrochemical study of thiols and disulfides using modified electrodes
Journal Article
·
· Anal. Lett.; (United States)
The electrochemical oxidative behavior of cysteine and several disulfides, such as cysteine, lipoic acid and disulfiram, have been investigated using a carbon paste (EPC) and a modified carbon paste (EPCM) electrode. The study has permitted the differentiation of the oxidative behavior of the thiol and of the disulfides. Modification of the carbon paste, by incorporating cobalt(II) phthalocyanine, offers interesting properties due to the electrocatalytic capability of the electrode. Using these types of electrodes the different molecules have been quantitatively determined at concentrations as low as 2.10/sup -7/ M. 14 references, 2 figures, 1 table.
