摘　　要：研制了电化学聚合制备烟酸分子印迹聚邻氨基酚敏感膜传感器，并对分子印迹膜的结构和性能进行了探讨与研究．在弱酸性条件下，以邻氨基酚为单体，烟酸为模板分子，用循环伏安法电聚合成膜制备传感器．该传感器对烟酸具有良好选择性和敏感度，用恒电位计时安培法，烟酸浓度在2．0～5．0mmol／L范围内与电流增量成线性关系，加标回收率在92％～104％之间．A sensitive nicotinic sensor based on molecularly imprinted electropolymer of O-aminophenol was proposed, and its configuration and performance were studied. Under the condition of weak acidity, the sensitive film was prepared through the electropolymerization of O-aminophenol on a platinum electrode in the presence of template （nicotinic）. The sensor exhibited good selectivity and sensitivity to nicotinic. A linear relationship between the current and the concentration was found in the range of 2. 0-5. 0 mmol/L The sensor has been applied to the analysis of nicotinic in samples with recovery rates ranging from 92% to 104%
