摘要: Molecularly imprinted polymers are often used in aqueous medium order to recognize specifically a target molecule. The molecular recognition is usually based on hydrogen bonding. In this case, water molecule presents serious competition towards the study, sorption by molecularly was studied medium. were specific for iprodione fungicide and prepared using 24 full factorial experimental design. They synthesized EGDMA or TRIM as crosslinker, methacrylamide styrene functional monomer bulk precipitation polymerization. isotherms established range of activities 0.05–0.90 at 25 °C. kinetics modeled Peleg's equation. This model shows that having highest capacities have high values imprinting factor. Guggenheim–Anderson–de Boer isotherm equations fit equilibrium data corresponding parameters calculated. with higher than those due hydrophobicity latter. Peleg satisfactorily non-imprinted polymers. results obtained from both practically coincident. Principal component analysis chemometric tool demonstrate polymer low adsorption energy capacity retention could be applied extract media.
