摘要
采用4种不同系列的典型金属有机骨架(MOFs)、MIL-101(Cr)、MOF-303(Al)、2-甲基咪唑锌和氨基苯二甲酸锆分别作为固相萃取功能材料,基于分散固相萃取-滤膜分离模式,实现对水体中极性差异较大的半挥发性有机物(SVOCs)双酚A和4-壬基酚的高效特异性吸附-固相萃取-液相色谱检测。结果表明,MIL-101(Cr)和MOF-303(Al)分别针对水相体系中弱极性SVOCs和强极性目标物具有更优异的固相萃取回收效果,氨基苯二甲酸锆可实现对强极性目标物的特异性萃取回收。
Four dfferent series of metal-organic framework(MOFs),MIL-101(Cr),MOF-303(Al),2-methylimidazole zinc and zirconium aminobenzoate,were used as solid phase extraction functional materials.Based on the dispersion solid phase extraction and filter membrane separation method,the determination of bisphenol A and 4-nonylphenol,which were semivolatile organic compounds(SVOCs)with diferent polarity in water,was realized by specific adsorption,solid phase extraction and liquid chromatography.MIL-101(Cr)and MOF-303(Al)have better solid phase extraction recoveries for weak polar SVOCs and strong polar targets in aqueous systems,respectively.Zirconium aminobenzoate can be used for specific extraction and recovery of highly polar objects.
