采用反相液相色谱法对环境水体中4种氨基苯磺酸类污染物进行分离分析。方法回收率在93.3%～97.5%之间,相对标准偏差为1.1%～2.4%。邻氨基苯磺酸、间氨基苯磺酸、对氨基苯磺酸和2,5-二氨基苯磺酸的方法检出限分别为0.5,0.5,0.2,0.8 mg/kg。该方法可以实现环境水体中氨基苯磺酸类污染物的准确定量。 The reversed-phase liquid chromatography was used to separate and analyze four kinds of aminobenzene sulfonic acid pollutants in environmental water. The recoveries of the method ranged from 93.3% to 97.5% with relative standard deviations of 1.1% to 2.4%. The detection limits of o-aminobenzenesulfonic acid, m-aminobenzenesulfonic acid, p-aminobenzenesulfonic acid and 2,5-diaminobenzenesulfonic acid were 0.5, 0.5, 0.2 and 0.8 mg / kg, respectively. The method can realize accurate quantification of aminobenzene sulfonic acid pollutants in environmental water.
