摘　　要：本文使用纳米金制备出三种纳米金修饰电极。考察了不同电极对对苯二酚响应特性及响应线性范围。实验结果表明:在pH值=6.0的磷酸盐缓冲溶液中,使用滴涂法制备的纳米金/壳聚糖复合膜修饰电极对对苯二酚的催化响应更为显著,在0.2×10-4~1.6×10^(-4)mol/L浓度范围内,其氧化峰电流与对苯二酚浓度呈良好的线性关系,具有制备对苯二酚传感器的前景。Three kinds of Au nano - particles modified electrodes were fabricated. The electrochemical characteristics and the linear scope of eleetroeatalytie oxidation to p - benzenediol at different modified electrodes were studied. In 0.1 mol/L PBS buffer （pH = 6.0）, experiment results showed that Au nano -partieles/ehitosan electrodes prepared by dispensing method had an excellent linearity response between oxidation current and concentration of p - benzenediol in the range of 0.2×10-4-1.6×10-（-4）mol/L, whieh gave the promising way for fabricating p - benzenediol biosensor.
