用电聚合的方法在金电极上制备了以妥拉苏林为模板分子的自组装邻氨基硫酚分子印迹膜传感器.通过差分脉冲伏安法研究传感器对妥拉苏林的响应特性,结果表明在优化的实验条件下,此传感器的峰电流响应值与妥拉苏林浓度在0.4～5μg·mL-1(r=0.9986)和5～120μg·mL-1(r=0.9953)范围内保持良好的线性关系,检测限为0.18μg·mL-1;相对标准偏差约为2.47%,响应时间约为3min.传感器具备较好的选择性和稳定性,初步用于人体尿液中妥拉苏林的分析,获得了较满意的结果. A novel self-assembled o-aminothiophenol molecularly imprinted membrane sensor with tolazarin as a template was prepared by electropolymerization on a gold electrode.The response of the sensor to tolazulin was studied by differential pulse voltammetry Under optimized experimental conditions, the peak current response of the sensor and torathulin in the range of 0.4 ~ 5μg · mL-1 (r = 0.9986) and 5 ~ 120μg · mL-1 (r = 0.9953) The detection limit was 0.18μg · mL-1, the relative standard deviation was about 2.47%, and the response time was about 3min. The sensor has good selectivity and stability, Analysis, obtained more satisfactory results.
