Liu-Mei-hua1,Qiu Bin2,Chen Guo-nan2,Chen Xi 2,3(1.Fuqing Branch of Fujian Normal University,Fuqing,Fujian,350300,China; 2.Key Laboratory of Analysis and Detection Technology for Food Safety(Fuzhou University),Ministry of Education,Department of Chemistry,Fuzhou University,Fuzhou,Fujian,350002,China; 3.State Key Laboratory of Marine Environmental Science,Xiamen University,Xiamen,Fujian,361005,China)  
In this paper,the 17β-Estradiol molecularly imprinted composite membrane through UV initiation was prepared by using porous cellulose acetate membrane as support.The selective binding properties and separation capacity of the membranes were investigated.The results showed that the 17β-Estradiol molecularly imprinted composite membrane had high binding capacity for 17β-Estradiol,the binding amount Q for 17β-Estradiol was 10.2 μmol/g and separation factor was 4.7 for 17β-Estradiol/17α-ethinylestradiol.Permeation experiment results showed that the molecularly imprinted composite membrane could separate 17β-Estradiol from 17α-ethinylestradiol.The bonding force between 17α-ethinylestradiol and the membrane was weaker than the template.
