英文摘要 | A zirconium (IV)-based metal organic framework material (MOF-808) has been synthesized in a simple way and used for extraction of phenoxyacetic acids in complex samples. The material has good thermal and chemical stability, large specific surface area (905.36 m²/g) and high pore size (22.18 Å). 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 π-π and hydrophobic interactions. The characteristics make the material very suitable for extraction of certain compounds with 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 ug·L-1 and a low detection limit of 0.1-0.5 ug·L-1 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 intraday and interday were between 1.8-3.8% and 4.3-6.9%, and the recoveries of spiking were between 77.1%-109.3%. The results showed the material is a desired substituent for the extraction of compounds with benzene ring structure containing carboxyl groups. |
