Preparation of molecularly imprinted polymer foam and selective adsorption and separation of cyhalothrin

In this paper, the stable water-in-oil type Pickering HIPEs was prepared with hydrophobic silica particles and nonionic surfactants Hypermer 2296, and then MIPFs with regular open pore structure were prepared with LC as the template molecule, AM and PEGDMA as the polymeric precursor.The behavior modification and mechanism of selective adsorption and separation of MIPFs for LC were studied using static adsorption experiment, and the influence of MIPFs structure for adsorption had also been researched. The results showed that the adsorption of MIPFs for LC was monolayer adsorption process and belonged to the level 2 dynamic model. The adsorption quantity of MIPFs for LC showed that MIPFs for LC had the good selective recognition ability, so MIPFs can effectively separated the residued LC from food, and improve the precision of the test for polyester residues.
