分散液-液微萃取(DLLME)是一种微型化液相萃取技术,是在一定体积的样品溶液中,快速注入含有萃取剂的分散剂,轻轻振荡,形成乳浊液体系而实现萃取,经离心后吸取聚积在试管底部的萃取剂,直接进样分析.使得目标分析物的富集倍数更高,非常适合进行痕量分析.传统的DLLME使用的提取溶剂大部分是一些含氯溶剂,毒性较高,容易挥发.离子液体以其独特的理化性质作为一种绿色溶剂替代传统DLLME中的提取溶剂.杀菌剂是使用量较多的农药,其残留通过喷雾、废水排放、土壤渗透等途径造成地下和地表水污染,给人们的身体健康造成危害.欧盟的饮用水法则(EC/98/
Dispersion liquid-liquid microextraction (DLLME) is a miniature liquid-phase extraction technology, which is to inject the dispersant containing extractant rapidly into a certain volume of sample solution, shake gently and form an emulsion system to achieve extraction. After centrifugation, the extractant accumulated in the bottom of the tube is taken and directly injected into the sample analysis to make the enrichment factor of the target analyte higher, which is very suitable for trace analysis. The traditional extraction solvents used by DLLME are mostly chlorinated solvents, Toxicity and volatility.Ionic liquid with its unique physical and chemical properties as a green solvent instead of the traditional DLLME extraction solvent.Fungicide is a more pesticide use, the residual through the spray, wastewater discharge, soil infiltration and other means Causing underground and surface water pollution, causing harm to people’s health.The EU drinking water law (EC / 98 /
