研制了电化学聚合制备尼古丁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,尼古丁为模板分子,用循环伏安法电聚合成膜制备传感器.该传感器对尼古丁具有良好的选择性和敏感度,用恒电位计时安培法,尼古丁浓度在4.0×10-7～3.3×10-5mol/L范围内与电流增量成线性关系,检测下限为2.0×10-7mol/L,加标回收率在99%～102%之间. A nicotine molecularly imprinted poly-o-aminophenol sensor was developed by electrochemical polymerization, and the structure and properties of the molecularly imprinted membrane were investigated. Under the condition of weak acidity, o-aminophenol was used as a monomer and nicotine as a template Was prepared by cyclic voltammetry electropolymerisation.The sensor has good selectivity and sensitivity to nicotine.Using the potentiostat-time amperometry, the nicotine concentration is in the range of 4.0 × 10-7 ~ 3.3 × 10-5mol / L Within a linear relationship with the current increment, the detection limit of 2.0 × 10-7mol / L, spike recovery was between 99% to 102%.
