| 摘 要： | 利用可溶性砷（包括有机砷、砷的无机含氧化合物）和硫化砷的特性进行砷的形态分析。在２ｍｏｌ／Ｌ盐酸中提取可溶性砷，与硫化砷进行分离，分别测定总砷和可溶性砷后差值为硫化砷，在９ｍｏｌ／Ｌ硫酸－碘化钾溶液中用苯萃取砷的无机含氧化合物与有机砷进行分离，可分别测定有机砷的砷的无机含氧化合物。

| Abstract: | Chemical state of As was analysed,on the basis of features of soluble As and arsenic sulfide.In 2 mol/L hydrochloric acid solution ,soluble As was separated with arsenic sulfide.In 9 ml/L hydrochloric acid-potassium iodide solution,inorganic oxide of As was extracted with benzene,and separated with organic As.Then,different chemical states of As were determined. |
