连续流动液膜萃取中液膜有机溶剂的选择
Selection of Organic Solvents in Continuous Flow Liquid Membrane Extraction
【摘要】 以具有不同极性的环境内分泌干扰物双酚A、辛基酚和壬基酚为模型化合物 ,对连续流动液膜萃取中用作液膜的有机溶剂进行了选择 ;结果表明 ,不同极性的有机溶剂对于极性不同的化合物的萃取效率明显不同。
【Abstract】 The effects of organic solvents of liquid membrane on extraction efficiencies of analytes with different polarity in continuous flow liquid membrane extraction was studied using bisphenol A,4-tert-octylphenol and4- nonylphenol as model compounds.Experimental results indicated that a higher extraction efficiency could be achieved by using organic solvents with proper polarity.
