离子色谱法测定高浓度氯水中的氟

Determination of F-in the high concentration Cl-water by Ion Chromatography

本文采用Ag+离子柱法去除高浓度氯水中的氯,当水样流经Ag+离子型柱时,Cl-和Ag+结合生成AgCl沉淀,用氨水溶解AgCl沉淀,让Ag+离子柱再生成K+离子型柱,最后用Ag+离子型柱法测定真实样品中的氟含量。应用于真实样品分析时,发现测得的数据结果比较满意。

This research adopted the Ag~ to wipe off the high concentration Cl- which hide in water, when the sample flowed through the Ag＋ ,the Cl- is combined in Ag＋ and made the precipitate of AgCl, Used ammonia to dissolve the precipitate of AgCl, the reborn process we disposed it to the K＋ and determined the content F- in samples. It was satisfactory with the test results when this method was used to analysis the samples.
