Abstract
A new molecularly imprinted polymer, which can be used for selective adsorption of chloramphenicol (CAP) from aqueous solutions, was successfully prepared by precipitation polymerization. The adsorption kinetic curve, adsorption isotherm and selective adsorption were measured by static method. The adsorption kinetics of MIPs for CAP reached the equilibrium at about 11 hours. The maximum adsorption capacity was 43.395 mmol/g, and the MIP has much higher adsorption quantity than NIP. Competitive adsorption studies showed that MIP offers the advantages of selectivity toward CAP compared with NIP in the presence other antibiotics. The results showed that the MIP possessed good specific adsorption capacity and selectivity for CAP.
