Abstract:
Chloramphenicol imprinted polymers(MIPs)were prepared by thermal polymerization with chloromycetin as template molecule and isopropyl acrylamide as functional monomer. Their physicochemical properties were characterized by FE-SEM and FT-IR. The effects of temperature,pH,initial concentration and equilibrium time on the adsorption performance were investigated by static adsorption experiments. The results showed that the adsorption equilibrium was reached at 25 ℃ after 2h and the pH of solution was 7. The theoretical maximum adsorption capacity was 127.8 mg/g. The adsorption mechanism was mainly single-molecular layer chemical adsorption process. The polymer provided good selective adsorption effect on chloramphenicol antibiotics.
