| Abstract: | A limit test method of heavy metal elements in liquid chlorine is introduced. The heavy metal ions react with sodium sulfide to generate brownish-black suspensions in weak acid （ pH = 3-4 ） condition. The method is illustrated in detail by taking the determination of lead standard solution as an example. |
