摘要: An amperometric sensor based on nano-Au thin films was fabricated, by means of which a fast response to 4-chlorophenol (4-CP) can be achieved in the range mM concentrations. The nanostructured Au film prepared glassy carbon electrodes template-free, double-potential step electrodeposition technique. Its structural feature controlled well adjusting deposition time. detection 4-CP performed at +0.85 V with linear from 0.2 4.8 mM and limit 0.11 mM (S/N=3). Besides, effect concentrations electrochemical behavior investigated sweep voltammetry, differential pulse voltammetry impedance spectroscopy.
