摘要
以二氯甲烷为提取溶剂，超声提取水厂底泥中的三氯生，提取液经浓缩吹干后用流动相定容，以甲醇／水=90／10为流动相进行超高效液相色谱分析，从而建立了快速准确测定水厂底泥中三氯生含量的高效液相色谱法。该方法线性范围为0．5～80mg／L，回收率为92．89％～104．62％，最低检出限为0．1mg／L。采用该方法对一些水厂沉淀池和回收水池底泥中的三氯生进行了测定，并与采自周边环境中的样品进行了比较。
An ultra performance liquid chromatography （UPLC） method was established to determine the contents of triclosan in sludge of WTP. Triclosan in sludge was ultrasonically extracted with dichloromethane as the extraction solvent. The extraction solution was condensed first and then was blown dry and solved in mobile phase with constant volume. The obtained solution was analyzed by UPLC with a mobile phase of methanol/water =90/10（V/V）. Tile linear range is 0.5 to 80 mg/L and the recovery varies from 92.89% to 104.62%. The detection limit is 0.1 mg/L. The contents of triclosan in sludge from sedimentation tanks and recovery water tanks were analyzed while the contents of triclosan in environmental samples were analyzed for comparison.
