电沉积羧基化石墨烯修饰的玻碳电极电化学检测镉离子
Electrochemical detection of cadmium ion by electrodeposited carboxylated graphene modified glassy carbon electrode
摘要
Abstract
[Objective]In this paper,a novel method was developed for electrochemical detection of cadmium ion based on elec-trodeposited carboxylated graphene modified glassy carbon electrode.[Methods]First,the carboxylated graphene modified glassy carbon electrode was fabricated by electrodeposited method.Then,using this modified electrode as the working elec-trode,the effect of buffer pH,deposition time and deposition potential on the determination of cadmium ion was investigated by square wave voltammetry.Finally,the analytical performance of the method to detection of cadmium ion was studied un-der the optimal detection conditions.[Results]Experimental result showed that the linear range obtained by the modified e-lectrode was 5×10-7mol·L -1~7.5×10-5mol·L -1for cadmium ion with a detection limit of 3.6×10-7mol·L -1.[Conclu-sion]This method had good reproducibility and selectivity,which was possibly applied for detection of cadmium ion in the water samples and other samples.关键词
