The electrochemical reduction behavior of Mevinphos has been studied by using, differential pulse voltammetry, cyclic voltammetry,. The determination of mevinphos in spiked human urine samples is carried out by using polythiophene modified glassy carbon electrode. Mevinphos exhibited single,well-defined peaks at pH2.0 inBritton–Robinson (BR) buffer solution. The standard deviations of various spiked urine samples were found in between 0.060 to 0.20 and relative standard deviations were observed in between 0.50 to 1.21%.
