摘要：Zeolite-modified electrodes have been largely developed during the past two decades for several electrochemical applications i.e. electroanalysis, voltametric detection, indirect amperometric detection, potentiometric sensing. In this work, Ag-modified zeolite-expanded graphite-epoxy composite electrode (Ag-Z-EG-Epoxy) was synthesized, morphological and electrical characterized and applied for amperometric detection of 4-chlorophenol (4-CP) in aqueous solution. The analytical performance of the electrode subjected to the electrode sensitivity, the lowest limit of detection (LOD) and the relative standard deviation (RSD) was determined in neutral and alkaline medium, using cyclic voltammetry (CV), linear-scan voltammetry (LSV), differential pulsed voltammetry (DPV) and batch system analysis (BSA).
