摘要:
基于壳聚糖功能基体的电化学沉积,以久效磷为模板分子,在玻碳电极表面直接制备具有记忆功能的分子印迹电化学传感器.借助以氢键为主的弱的分子间作用力,实现久效磷在壳聚糖聚合基体内的印迹,而施加+0.6 V电压改变复合物成键的微环境可以实现洗脱.对分子印迹膜性质、洗脱方式等制备条件的考察,采用阳离子型电化学探针三氯化六铵合钌,研究分子印迹传感器对久效磷的电化学响应特性.结果表明,所制备的久效磷分子印迹电化学传感器具有较高的选择性,对久效磷的检测限可达0.1μmol.L-1.
Abstract:
A molecularly imprinted electrochemical sensor(MIP/GCE) of good memory capacity was developed.Using moncrotophos as template molecule,the compound of chitosan and moncrotophos were direct synthesized onto the surface of glass carbon electrode basing on electrodeposition of function matrix chitosan with the aid of hydrogen bond between chitosan and moncrotophos,the imprinted film was formed after the elution of moncrotophos from the co-deposited compound film by applying +0.6 V on the electrode to change the combination microenvironment.Cationic probe Ru(NH3)3+/2+6 was employed to study the optimal conditions of film formation and the electrochemical performance of MIP/GCE on moncrotophos.Result shows,the monocrotophos molecularly imprinted electrodeposition was of good selectivity and detection limit of 0.1 μmol·L-1 was obtained.
