摘要：
A comparative electrochemical study has been carried out of the electropolymerization of phenothiazine derivative,methylene blue (MB). Electrochemicals proporties of resulting electrocatalytically active methylene blue polymer (pMB) have been studied on three various carbon-based substrates; basal plane of highly oriented pyrolytic graphite (HOPG), pencilgraphite electrode (PGE) and carbon fiber micro electrode (CFE). Electrodes modified with the polymer (HOPG/pMB, PGE/pMB and CFE/pMB) have been prepared by potential cycling in aqueous electrolyte solution containing dissolved monomeric methylene blue Electrocatalytic activity of three developed electrode system towards hydrogen sulphide has been compared Develped electrodes have been further investigated as potential semsor for sulfhydryl-containing compounds.
