摘要
分散液-液微萃取技术是一种新型的、具有省时高效、有机溶剂耗用量少、对环境友好等特点的样品前处理技术。综述了分散液-液微萃取技术在我国有机污染物中的应用情况,涉及水中苯系物、农药残留物、多环芳烃、多氯联苯、氯苯类、环境激素类、氯酚类、硝基苯类、四乙基铅等,并展望其耦合应急监测仪器在突发性污染事故应急监测中得到应用。
Dispersive liquid-liquid microextraction(DILLME) is a novel sample-preparation technique,which can offer high enrichment factors from low volumes of water samples with several advantages of simplicity of operation,rapidity,low cost and environment friendly.The present review focuses on applications of DLLME for extraction organic analytes,including pesticide,PAHs,amines and nitrogenous compounds,phenols and other compounds.Finally,a future trend of DLLME with emergency monitoring equipment is developed in emergency monitoring of sudden environmental pollution accidents.
