石墨烯-壳聚糖修饰玻碳电极应用于环境水中五氯酚的测定
Application of Graphene-chitosan Modified Electrode for the Detection of Pentachlorophenol in Environmental Water
摘要
Abstract
The graphene-chitosan modified glassy carbon (CRG-CS/GC) electrode was prepared. Based on this, the electrochemical behavior of pentachlorophenol ( PCP) was investigated by cyclic voltammetry and differential pulse voltammetry. It was found that the oxidation current at CRG-CS/GC electrode is obviously larger than at GC electrode, indicating that the CRG-CS/GC electrode has strong adsorption ability and can promote the electron transport. Then, the CRG-CS/GC electrode with the simple, sensitive, stable and reliable property was developed for the detection of PCP. Using this electrode, analytical performance with the linear range from 1. 0 × 10 -7 to 1. 0 × 10 -5 mol/L and a limit of detection to 2. 3 × 10-8 mol/L were obtained. The electrochemical sensor with the CRG-CS/GC electrode was successfully employed to detect PCP in several water samples. The recovery can reach 97% ~ 103% .关键词
