| 中文摘要: |
| 将分子印迹技术与电化学传感器相结合，以双酚A（BPA）为模板分子，吡咯为功能单体，在基于多壁碳纳米管修饰的玻碳电极表面制备了一种对BPA具有选择性识别的分子印迹聚合物，并进行相关试验条件的优化。在最优条件下构建了BPA-MWCNTs-COOH分子印迹电化学传感器，以铁氰化钾K3［Fe(CN)6］为电化学探针，测得BPA在0.01 μmol/L~17 μmol/L范围内线性良好，检出限为0.006 μmol/L。将该方法用于湖水样品测定，结果为未检出，加标回收率为97.8%～115%，RSD＜5%。 |
| 英文摘要: |
| Combining molecular imprinting technology with electrochemical sensors， a molecularly imprinted polymer with selective recognition of bisphenol A (BPA) was prepared on the surface of glassy carbon electrode modified by multi-wall carbon nanotubes， with bisphenol A (BPA) as the template molecule and pyrrole as the functional monomer， and the related experimental conditions were optimized. The BPA-MWCNTs-COOH molecularly imprinted electrochemical sensor was constructed under optimal conditions. With potassium ferricyanide as the electrochemical probe， BPA had good linearity within the range of 0.01 μmol/L~17 μmol/L， the detection limit was 0.006 μmol/L. This method was used to the determination of surface water in Jinghu Lake in North China University of Science and Technology. The results were not detected. The recoveries were 97.8%~115%， and RSD＜5%. |
