Abstract:
A novel hybrid material (ZIF-7-NH2@MIP) combining high adsorption capacity of amino-functional zeolitic imidazolate framework and specific recognition ability of dual-template molecular imprinted polymer was synthesized. The prepared ZIF-7-NH2@MIP was characterized by a range of instrumental techniques and combined with high performance liquid chromatography for the detection of four phthalate esters. The limits of detection of the four PAEs were below the maximum residue limit of GB 3838-2002 in China, ranging from 0.04 to 0.08 mu g L-1. The recoveries of the three real samples of mineral water, carbonated drinks and pulpy juices spiked at 10 mu g L-1 were 88.68-98.58% and the relative standard deviations was 1.19-3.40%. The above results showed that the obtained absorbent exhibited many advantages for extracting analytes in aqueous solution especially complex environment due to the combination of the superior hydrothermal and large specific surface area of the amino-functionalized ZIF-7-NH2 and the specific identification of the dual-template molecular imprinted polymer.
