摘要
用抑制型离子色谱法探讨了ＳｅＯ３（２）和ＳｅＯ４（２－）等七种阴离子的洗脱行为，讨论了共存阴离子的干扰及其消除，建立了测定水中ｓｅＯ３（２－）和ＳｅＯ４（２－）等阴离子的方法．ＳｅＯ３（２－）和ＳｅＯ４（２－）的检测限分别为４０μｇ／Ｌ和５０μｇ／Ｌ．
The elution character of seven kinds of anion was investigated by inhibitory ionic colour spectrum, the disturbance aam elimination of coexisting anions was discussed,.the method to determine SeO3(2-) and seO4(2-) in water wasset up. The examing linmits of SeO3(2-) and SeO4(2-) was 40μg/L and 50μg/L, respectively
