살충성 O,O-Dimethyl-O-(3-Metyl-4-Nitrophenyl)-phosphorothioate (Sumithion^�)의 전기화학적 환원반응에 미치는 Micell의 영향 = The Micell Effect on the Electrochemical Reduction of Insecticidal O,O-Dimethyl-O-(3-Metyl-4-Nitrophenyl)-phosphorothioate (Sumithion^�)

다국어 초록 (Multilingual Abstract)

The electrochemical reduction of sumithion in various surfactants, NaLS, CTABr, Triton X-100 and in acetonitrile solution has been examined by DC, DP polarography and cyclic voltammetry (CV). Especially, in anionic surfactant, NaLS solution, the height of reduction wave is dramatic eliminated and half-wave potentials are shifted to strong negative potential (-2.7 volt vs. Ag-AgCl) by repulsion of nitro group in sumithion and anionic micell surfaces. The processes of reduction of sumithion were irreversibly electrochemical mechanism and the result of the reaction at high cathodic potential (-2.7v. vs. Ag-AgCl), O,O-dimethyl-O-(3-methylhydoxyaminophenyl) phosphorothioate is formed as major product via O,O-dimethyl-O-(3-methylnitrosophenyl) phospho-rothioate in NaLS micell solution.
