【Abstract】 Prussian blue modified film doped with Cu( Cu/PB/GC) was prepared by using cyclic voltammetric( CV) method. The electrochemical behavior of 3-nitrophenol was investigated by using( CV),chronocoulometry and electrochemical impendence method.The results showed that the reduction peak current of the 3-nitro phenol was significantly increased and the electrode reaction was diffusion-controlled.The diffusion coefficient D is 1. 64× 106cm~2·s-1,while transfer coefficient is 0. 249,the electrode can be used for rapid detection of 3-nitrophenol.更多还原
