工业废水中三硝基化合物的测定

Study on the measuring methods of the concentration of 3-nitro compands in the waste water of industry

采用乙醚萃取,氯代十六烷基吡啶—亚硝酸钠分光光度法测定废水中的三硝基化合物,分析结果表明,该方法有较高的灵敏度和准确度。

The 3-nitro compands in waste water was determined by ethyl ether-cetylphridine chloride-sodium nitrite speclrophotometry.The result showed that this method is sensitive and exact.
