| 英文摘要 | A zirconium(iv)-based metal-organic framework material (mof-808) has been synthesized in a simple way and used for the extraction of phenoxyacetic acids in complex samples. the material has good thermal and chemical stability, large specific surface area (905.36m(2)/g), and high pore size (22.18 angstrom). besides, it contains a large amount of zr-o groups, easy-to-form zr-o-h bond with carboxyl groups of phenoxyacetic acids, and possesses biphenyl skeleton structure, easy to interact with compounds through p-p and hydrophobic interactions. these characteristics make the material very suitable for the extraction of certain compounds with a high extraction efficiency and excellent selectivity. the extraction conditions were optimized, and then an analytical method was successfully established and applied for analysis of actual samples. the solid-phase extraction method based on prepared material had a wide linear range of 0.2-250 mu g/l and a low detection limit of 0.1-0.5 mu g/l for four phenoxyacetic acid compounds including 2,4-dichlorophenoxyacetic acid, 2-(2,4-dichlorophenoxy) propionic acid, 4-chlorophenoxyacetic acid, and dicamba. the relative standard deviations of intra-and interday precision were 1.8-3.8 and 4.3-6.9%, and the recoveries after spiking were between 77.1 and 109.3%. the results showed that the material is a desired substituent for the extraction of compounds with benzene ring structure containing carboxyl groups. |
