摘要：

This study presents a new approach for rapid detection of sulfide using a glassy carbon electrode (GCE) modified with alizarin (Az) and reduced graphene oxide (rGO) nanosheets. The fabricate Az-rGO/GCE sensor shows a notable electrocatalytic activity to sulfide oxidation. The currents of anodic peak centered at +465 mV in 0.2 M pH 7.0 phosphate buffer were related linearly to the concentrations of sulfide, based on the cyclic voltammetric studies. The linear range was 0.002-3.28 mM, and the detection limit was 1 mu M. The proposed method was applied in sulfide determination of hydrogen sulfide pretreated fruits, and the method was also verified with recovery studies. (C) 2015 Elsevier Ltd. All rights reserved.
