基于聚谷氨酸修饰玻碳电极的甲基对硫磷电化学传感器
A Methyl Parathion Electrochemical Sensor Based on Poly(glutamic acid) Modified Glass Carbon Electrodes
摘要
Abstract
A simple electrochemical sensor was developed for detecting methyl parathion (MP) based on electropolymerization of L-glutamic acid on the glassy carbon electrode.The redox behavior of MP on the sensor was investigated by cyclic voltammetry,and the determination of methyl parathion was performed with differential pulse voltammertry.A highly linear current response to methyl parathion was obtained in the concentration range from 5.0 × 10ˉ7 to 7.5 × 10ˉ4 mol/L.A detection limit of 1.0 × 10ˉ9 mol/L at a signal-to-noise ratio of 3 was attained.The method could be applied to the determination of methyl parathion in real samples.关键词
