| 摘 要： | 用电化学聚合的方法制备了聚N，N-二甲基苯胺高分子膜修饰玻碳电极。在碘离子存在的情况下，溶液中的Pb^2＋与I^-形成的络合阴离子，由于静电吸附作用被富集到带正电荷的修饰电极表面，然后用线性扫描伏安法进行测定。实验优化了各种参数（如富集底液、富集时间等），并考察了其他金属离子对铅的测定的影响。在最佳实验条件下，铅离子浓度在5×10^-7-5×10^-5mol／L的范围内与氧化峰电流呈线性关系，最低检出限为5×10^-7mol／L。将该方法应用于实际水样的测定，结果满意。 |

| Abstract: | Poly N,N-dimethylaniline modified glassy carbon electrode was prepared by electropolymerization.In the presence of I-,the complex anion formed from Pb2+ and I-in the solution was accumulated onto the modified electrode surface by the electrostatic adsorption,and then determined by the linear sweep voltammetry.The experimental parameters,such as the accumulation solution and accumulation time were optimized,and the other metal ions interference to the determination was also studied.Under the optimum conditio... |
