Preparation of chloramphenicol imprinted polymer membranes and its adsorption characteristics
摘要
Abstract
By using chloramphenicol as template, 4-vinylpyridine as functional monomer and porous polypropylene non-woven as the support membrane, chloramphenicol imprinted polymer membranes with predominant recognition and selectivity are prepared through in-situ polymerization by UV irradiation. The interaction between chloramphenicol and functional monomer is verified by UV-visible spectroscopy. The morphologies of chloramphenicol imprinted polymer membranes with different PEG dosage are observed by the scanning electron microscopy (SEM). The binding characteristics of the imprinted membranes are studied by the equilibrium binding experiments and specific adsorption experiments. The results show that hydrogen bonding is formed between template molecule and functional monomer. When the mass fraction of PEG is 16% , the prepared imprinted polymer membranes have perfect morphologies and uniform pore structure. It is found that the imprinted polymer membranes show good recognition characteristics to chloramphenicol and the max binding amount reached 22.83 μmol/g.关键词
