| 摘 要： | 研究了镀铋膜电极微分电位溶出分析法测定水中铅的方法,考察了该法测定铅的条件.结果表明,在HAc-NaAc介质中铅可在镀铋膜电极上得到灵敏的微分电位溶出峰,结合微波富集方法,检出限达0.003 mg/L,利用标准加入法对水样中痕量铅进行测定,避免了镀汞膜电极带来的健康与环境危害,结果较满意.

| Abstract: | A novel substitutive differential potential stripping analysis for the determination of trace lead via bismuth-film electrode has been studied. Its determination conditions have also been investigated. The results show that Pb in the HAc-NaAc buffer solution can reach the sensitive differential potential stripping analysis peak on bismuth-film electrodes. Combining with microwave enrichment,a detection limit of 0.003 mg/L is obtained. The method has been applied to the determination of trace lead in water samples by standard adding method. It prevents health and environment hazards caused by mercury-film electrode from happening,with satisfactory results. |
