| Abstract: | The method of determination of F-、Cl-、SO2-4and NO-3 in the waste acid cleaning solution by ion chromatography was introduced.The interferences of metal ions and residual acid liquor in waste acid cleaning solution were removed,and the pollution of ion chromatography column was also reduced by a certain pretreatment method.The concentrations of F-,Cl-,SO2-4 and NO-3 in the waste acid cleaning solution were determined according to the optimal experimental conditions.The detection limits of F-,Cl-,SO2-4 and NO-3 were 0.04,0.09,0.71,0.27mg/L,respectively.The relative standard deviations were 0.52%—1.64%.The average recoveries were 94%—109%. |
