| 摘 要： | 采用电化学聚合的方法制备了聚1,8-萘二胺修饰玻碳电极,建立了吸附富集-阳极溶出伏安法测定痕量Hg2+的新方法.优化了各种实验参数(如富集底液的pH,富集时间等),并考察了其它离子的干扰.在最佳实验条件下,Hg2+在0.001～0.1 mg/L及0.1～5.0 mg/L质量浓度范围内均与溶出峰电流成良好的线性关系,检出限为0.0005 mg/L.该法可用于实际工业废水中汞的测定. |

| Abstract: | A new method for the determination of trace Hg2+ by adsorptive accumulation-anodic stripping voltammetry was established using an electropolymerized poly(1,8-diaminonaphthalene) modified glassy carbon electrode.The parameters,such as the pH of accumulation solution,accumulation time etc were optimized.The interferences of other ions were also studied.Under the optimum experimental conditions,the peak current of Hg linearly increased with increasing the concentration of Hg2+ from 0.001 mg/L to 5 mg/L,and the... |
