摘要
选择Agilent Bond Elut Plexa作为固相萃取柱,结合高效液相色谱测定固体废物浸出液中12种苯酚类化合物,通过试验优化条件,使目标物在0.100 mg/L^10.0 mg/L范围内线性良好,方法检出限在0.004μg/L^0.068μg/L之间,3个质量浓度水平加标回收率为78.0%~105%,测定6次结果的RSD为0.7%~5.0%。将该方法用于测定江苏省某工业园区污水处理企业5个废水处理污泥样品,结果 2,4,6-三氯苯酚和2,4-二硝基苯酚检出。
A method has been established to determine twelve kinds of phenolic compounds by Agilent Bond Elut Plexa for the extraction column and high performance liquid chromatography.Good linearity was achieved in the concentration range of 0.100 mg/L^10.0 mg/L for the twelve target compounds by optimiazing the pretreatment process and the instrument conditions,the method detection limit for each compound ranged from 0.004μg/L to 0.068μg/L,the recovery for three mass concentration level was beteen 78.0%~105%,the RSD of six times were 0.7%~5.0%.The method was applied to the determination of five wastewater treatment sludge samples in a sewage treatment enterprise of an industrial park in jiangsu Province,the result showed that the 2,4,6-Trichlorophenol and 2,4-dinitrophenol were detected.
