Highly Selective Perchlorate Coated-Wire Electrode (CWE) based on an Electrosynthesized Dixanthylinum Dye and Its Application in Water Samples

Abstract

The fabrication, performance, and utilization of perchlorate coated-wire electrode (perchlorate-CWE) based on dixanthylinum dye concerning the response towards perchlorate ions was defined. The recommended electrode exhibits a Nernstian response for perchlorate by a wide concentrations range of 1.0×10−6 to 6.1×10−2 M, with a slope of -57.4 mV in comparison to other anions. The limit of detection is 5.0×10−7 M. It has a quick response time of ~4 seconds. The recommended electrode shows adequately good discriminating ability towards perchlorate ions in comparison to other anions and it is profitably applied to the direct determination of perchlorate ions in water samples.
