Electrochemical determination of methyl parathion using a modified electrode

摘要: Electrochemical studies of pesticides using various electrode systems attain prominence in recent years because their application trace determinations. Cyclic voltammetric methyl parathion on a glassy carbon at pH 50% aqueous ethanol medium were carried out. Influence led to the selection 1.0 as best for electroanalysis parathion. The number electrons transferred was determined controlled potential coulometry. On basis results probable reduction mechanism proposed. polypyrrole deposited and sodium montmorillonite clay modified electrodes presence cetyl trimethyl ammonium bromide clay-modified peak around −0.2 V selected stripping analysis owing maximum current response. experimental parameters optimized differential pulse mode. A calibration plot m...
