| 以铜离子为模板离子,多巴胺为功能单体,采用电聚合法在石墨烯修饰碳电极表面成功制备对铜离子有高选择性和高灵敏性的印迹电化学传感器。采用差分脉冲伏安法和循环伏安法对该印迹传感器的电化学行为进行详细研究。优化检测条件,该印迹电化学传感器的响应电流与铜离子浓度的负对数在5×10-6~5×10-11 mol/L的浓度范围内呈良好的线性关系,最低检测限为1.0 × 10-11mol/L。该印迹电化学传感器成功用于实际水样中的微量铜离子分析。 |
| 英文摘要: |
| A novel copper ion imprinted sensor was prepared for sensitive and selective determination of copper with graphene as the modification material, copper ion as the template ion, and dopamine as the functional monomer. The ion imprinted electrochemical sensor was characterized by differential pulse voltammetry and cyclic voltammetry. The results showed that the imprinted sensor exhibits high sensitivity and selectivity toward copper ion. Under the optimized conditions, a good linear relationship was existed between the response current of the imprinted sensor and the negative logarithm of copper ion concentration in the range of 5.0 ×10-6~5.0×10-11 mol/L. The ion imprinted electrochemical sensor was successfully used for the detection of trace copper ion in sample water. |
