N2 - An electrochemical sensor for the detection of methyl parathion (MP) was developed based on electrochemically reduced graphene oxide (ERGO) modified GCE (ERGO/GCE). ERGO was characterized by Raman and IR spectroscopy, scanning electron microscopy and atomic force microscopy. The electrochemical reduction of MP was investigated using cyclic voltammetry technique in phosphate buffer (pH 7). Using square wave voltammetry, a linear calibration curve for the detection of MP was obtained in the concentration range from 3.0 x 10-8 M-2 x10-9 with a detection limit of 8.87 x 10-10 M. The selectivity of the ERGO/GCE was tested in the presence of a few metal ion and organic interfering species. Real sample analysis using potato samples had been carried out.
