离子色谱法测定水中5种消毒副产物和6种阴离子

Determination of Five Disinfection By-products and Six Anions in Drinking Water by Ion Chromatography with A New Type Column

利用新型离子色谱柱AS23柱对水中5种消毒副产物:二氯乙酸(DCAA)、三氯乙酸(TCAA)、亚氯酸盐(ClO-2)、溴酸盐(BrO-3)、氯酸盐(ClO-3)和6种常见阴离子:F-、Cl-、NO-2、Br-、NO-3、SO2-4进行检测,通过实验研究,测试方法对饮用水中11种被测物的最低检测限为0.42～15.55μg/L,加标回收率为89.30%～115.12%,适合于同时检测饮用水中消毒副产物和常见阴离子。

A method for simultaneous determination of five disinfection by-products DCAA,TCAA,ClO^-2,BrO^-3,ClO^-3and six anions： F^-, Cl^-,NO^-2,Br^-,NO^-3,SO^2-4 in drinking water was developed by ion chromatography with AS23 column in this paper. The result of analyzing eleven analyte showed that the detection limits were between 0.42-15.55μg/L, the recoveries were between 89.30%-115.12%. This method was suitable for simultaneously determination of disinfection by-products and common anions in drinking water.
