摘要
目的建立能同时测定饮用水中亚氯酸盐、溴酸盐和氯酸盐的方法。方法采用离子色谱法,选用IonPacAS9分离柱,10.0mmol/LNa2CO3为淋洗液,水样经沉淀脱色后,过滤进样分析。结果方法的相关性好(r>0.9992),线性范围广,检出限低(0.0028～0.0087mg/L),RSD<2.82%,样品加标回收率为92.6%～102.6%。结论该法干扰小,灵敏度高,结果准确、操作简便,适合饮用水中亚氯酸盐、溴酸盐和氯酸盐的同时检测分析。
[Objective]To establish a method for simultaneous determination of Chlorite,Bromate,Chlorate in drinking water.[Methods]Ion chromatography was applied.IonPac AS9 was selected as the separation column,10.0 mmol/L Na2CO3 as eluent.After deposition,decoloration and filtration,the samples was injected and analyzed.[Results]In this method,good relation （r0.9992）,broad linearity range,low detection limit （0.0028～0.0087 mg/L） were obtained （RSD%2.82）.The average recoveries rates were between 92.6% and 102.6%.[Conclusion]This method is simple,rapid,sensitive and accurate,with little interference.It is suitable for simultaneous determination of Chlorite,Bromate and Chlorate in drinking water.
