离子色谱法测定AgNO3中的微量Cl-、NO2-和SO42-
DETERMINATION OF CI- , NO2- AND SO42- IN AgNO3 BY ION CHROMATOGRAPHY
【摘要】 用离子色谱法测定AgNO3溶液中的Cl-、NO2-和SO42-,以5.0mmol/L Na2CO3-5.0mmol/L NaHCO3混合溶液作淋洗液,采用离子交换法将AgNO3转换成KNO3,以除去Ag+。讨论了NO3-对Cl-、NO2-和SO42-测定的影响。AgNO3溶液中Cl-、NO2-和SO42-的回收率分别为93.3%、108%和94%。
【Abstract】 After Ag+ being removed from AgNO3 solution by changing AgNO3 into KNO3, Cl- , NO2- and SO42- in AgNO3 solution were determined by ion chromatography with the eluant of 5. 0 mmol/L Na2 CO3 - 5. 0 mmol/L NaHCO3. The recovery is 93. 3% , 108% , and 94% , respectively.
