摘　　要：ＰＯＡＰ－Ｎｉ２＋膜电极对乙醇氧化表现出优越的电催化活性．乙醇氧化电流受到膜厚、膜中镍离子浓度、活化时间、电解质ｐＨ值及温度等条件的影响．选择合适的条件，可得到乙醇浓度与响应电流的线性关系．ＰＯＡＰ－Ｎｉ２＋可构成较理想的乙醇传感器，其线性范围、检测下限。POAP Ni 2+ films modified electrode can electrocatalyzes significantly the oxidation of alcohol. the modified electrode can be used as the electrochemical sensor for the detection of alcohol. But the oxidation of alcohol is effected by the thickness of films、the concentration of nickel ion in films、pH of electrolyte,as well as temperative. All of those conditions have been studied in order to achieve stable response current during the oxidation of alcohol, and the relation between concentration and current has been made. At last the major characteristic parameters, such as the low limitation of concentration、the response time、the ability of antiinterference et al,have been discussed.
