摘要
使用基于阳极溶出伏安法原理的便携式重金属检测仪,现场测定广州不同地区自来水的锌、镉、铅含量,分析比较了不同地区自来水中锌、镉、铅离子的含量,探讨了同一取水点不同时段取水样引起的测试结果差别,考察了水样保存期,结果显示水样保存期不能超过10天,最好尽快测试。
Using the portable metal analyzer which base on anodic differential pulse voltammetry, Discussing the different concentration of Zn2＋, Cd2＋, Pb2＋ in the tap water from different area in Guangzhou city, find out that the metal ions concentration of tap water from different zone, different time is different. Otherwise, the store time of the sample may affects the result, suggesting that the sample should analysis as soon as possible.
