Abstract

The Au/chitosan fiber was firstly prepared by electrospinning and chemical reduction method and used to modify BDD electrode for the detection of methyl parathion. The results indicated that Au/chitosan fiber-modified BDD electrode could improve the electrocatalytic activity, accelerate response, enhance the sensitivity, and reduce the detection limit, as compared with the bare BDD electrode. The repeatability and stability of Au/chitosan fiber-modified BDD electrode was also studied. For the detection of methyl parathion in the apple juice samples, Au/chitosan fiber-modified BDD electrode obtained favorable results and ideal recovery rate. [ABSTRACT FROM AUTHOR]
