摘要：

A sensitive electrochemical stripping voltammetric method for analyzing organophosphate (OP) compounds was developed using a carbon paste electrochemical (CPE) transducer. ON strongly adsorb on a CPE surface and provide facile electrochemical quantitative methods for electroactive OP compounds. Operational parameters have been optimized, and the stripping voltammetric performance has been studied using square wave voltammetry. The adsorptive stripping voltammetric response is highly linear over the 1-60 mu M methyl parathion range examined (2-min adsorption), with a detection limit of 0.05 mu mol/L (10-min adsorption) and good precision (RSD = 3.2%, n = 10). These findings can lead to a widespread use of electrochemical sensors to detect OP contaminates. (c) 2005 Elsevier B.V.. All rights reserved.
