    Abstract:

    A series of Luteolin complex molecular imprinted polymers(LUT-CIPs)were synthesized in water with coordination of Zn(II),using luteolin as dummy template, acrylamide (AM) as monomer and N, N?- methylene diacrylamide (MBA) as cross-linker,and the adsorption ability of LUT-CIPs were also studied. The results showed that:when n(luteolin-Zn2 )∶n(AM)∶n(MBA) was 1∶4∶30, the obtained LUT-CIPs possessed the highest adsorption properties, and the adsorption capacity for luteolin from ethanol phase reached 36.4mg/g ,selectivity coefficient of luteolin for apigenin was 5.09 and for rutin was 3.35. The adsorption process of luteolin in LUT-CIPs conforms to the Freundlich isothermal adsorption model and the quasi-second-order kinetic equation. The adsorption capacity was increased when adding metal salts to solution, the influence was Pb(Ac)2> Ce2(SO4)3> Bi(NO3)3> Cu(Ac)2> Mg(NO3)2> Zn(Ac)2> Ba(NO3)2> MnSO4> NiSO4> ZnSO4> CdSO4,the adsorption of adding Pb(Ac)2 was 2.48 times that of adding Zn(Ac)2,5.20 times that of adding nothing.
