Characteristics of Levofloxacin Imprinted Polymers Prepared via Thermal Polymerization Method

BING Na-Ci,XU Zhen-Liang~*,YANG Zuo-Guo,WANG Xue-Jun,FENG Jian-Li(Chemical Engineering Research Center,East China University of Science and Technology,Shanghai 200237)  
Molecularly imprinted polymers(MIPs) were synthesized via(thermal) polymerization method with levofloxacin(LVFX) as template and methyacrylic acid as functional monomer.The UV and IR spectra(indicated) that the MIPs could recognize LVFX molecule through hydrogen-bond and ionic-bond interactions.Scatchard analysis showed that two kinds of recognition sites were formed,and the maximum apparent binding capacities were 9.76 μmol/g and 25.75 μmol/g,respectively.The selective adsorption of LVFX on MIPs could be completed in 10 min.On the basis of isothermal binding thermodynamics,the absorption to the(template) was spontaneous,and ΔΔH=-1.18 kJ/mol and ΔΔS=-0.27 J/(mol·K).
