目前，测定矿泉水中的硫化物方法很多。本文选用阴离子交换法，方法简便快速、准确、灵敏度高，现介绍如下。材料与方法 （１）原理：硫化物与碘酸铅在ｐＨ＝５～８条件下反应生成硫化铅和碘酸盐离子。反应剩余的碘酸铅和生成的硫化铅沉淀经过滤除去，释放在溶液中的碘酸盐离?
At present, there are many ways to determine sulphide in mineral water. This selection of anion exchange method, the method is simple, fast, accurate, high sensitivity, are described below. Materials and Methods (1) Principle: Sulfide and lead iodate react at pH = 5-8 to generate lead sulfide and iodate ion. Reaction of the remaining lead iodate and lead sulfide precipitate was removed by filtration, the release of iodate in solution from?
