摘要
将分子印迹(Molecular Imprinting Polymer)和光电化学(Photoelectrochemical)传感器相结合,并利用激光直写技术生成CdS/Graphene,构建氨基甲酸乙酯分子印迹光电化学传感器。利用溶液聚合法制备氨基甲酸乙酯分子印迹聚合物,探究了分子印迹聚合物中各组分的摩尔比等因素对氨基甲酸乙酯的光电流信号的影响。实验结果表明,所设计的传感器对氨基甲酸乙酯浓度在0.0001~0.0075 mmol/L之间呈现良好的线性关系,检测限为0.08μmol/L,且其线性相关系数R^(2)为0.99184。
The molecular imprinting polymer was combined with the photoelectrochemical sensor,and the directlaser-writing technology was used to generate CdS/Graphene to study the molecularly imprinted photoelectrochemical sensor of ethyl carbamate.The molecular imprinted polymer of ethyl carbamate was prepared by solution polymerisation,and the influence of other conditions such as the molar ratio of each component in the polymer on the photocurrent signal of ethyl carbamate was explored.The experimental results show that the designed sensor has a good linear relationship between 0.0001 mmol/L and 0.0075 mmol/L for the concentration of ethyl carbamate in the designed sensor,with a detection limit of 0.08μmol/L,and its linear correlation coefficient R^(2)is 0.99184.
