Abstract
- Abstract: A molecular imprinted particle for Bisphenol A (BPA-MIP) was successfully used for selective recognition of BPA in the water. The contaminants such as 3, 3′, 5, 5′-Tetrabromobisphenol A (TBBPA), phenol and phenol red (PSP) were selected as the latent interferon to investigate the selectivity. The binding efficiencies of BPA-MIP for different phenols were explored at various initial concentrations in the single and mixed water. Various selective parameters such as K d , K and K' of BPA-MIP for BPA were calculated. The influences of humic acid (HA) and common ions on the BPA binding were investigated. A physical model was proposed to illustrate the selective binding performance. The results showed that BPA-MIP possessed strong selectivity for BPA in competitive water, while the other similar phenols had the influence for BPA binding at the order of TBBPA > phenol > PSP. The HA and common ions indicated little effect on the BPA binding process onto BPA-MIP. It was found that the molecular geometry and the hydrogen bonding interactions between the hydroxyl and carboxyl played an important role in recognizing the target molecular in the binding process.
