| 摘 要： | 本文探讨了HPIC—AS_3分离柱分离,Dionex2020i型离子色谱仪—电化学检测器测定水中微量CN~-的诸条件,并考察了干扰离子及CN~-络合物对CN~-测定的影响。采用两根AS_3分离柱串联的方法提高分辨率,150ppmCl~-对5ppbCN~-无干扰。方法检出限0.14PPb。5ppbCN~-11次测定结果相对标准偏差为1.2％。本法可用于地表水、地下水、污水及工业废水中氰离子的分析。

| Abstract: | Trace cyanide is seperated with HPICASa anion exchange column and detected with ion chromatography and electrochemical detector via silver electrode.Various analytical conditions are discussed. The detection limit for cyanide is 0.14ppb. The relative standard deviation is 1.2%, 5ppb cyanide is not interfered by 150ppm chlorides. This method can be used to determine ground surface water, underground water and industrial waste water. |
