Study on preparation and performance of rutin molecularly imprinted polymers
摘要
Abstract
A series of molecularly imprinted polymers (MIPs) were prepared by the molecular template technology in methanol/water ( V/V, 1/4) with rutin as the template molecule, methacrylic acid (MAA) or acrylamide ( AM ) as the functional monomer,ethylene glycol dimethacrylate(EGDMA)as a crosslinker,and azobisisobutyronitrile(AIBN)as evocating agent, respectively. The effect of the composition of polymerization systems of different functional monomer and dosage of functional monomer and crosslinker on the adsorption property of MIPs were studied.The character trials which involved the determination of the binding isothermal,the analysis of Scatchard plot carried out on the MIPs .Scatchard analysis showed that two classes of binding sites were produced in the polymermatrix and their dissociation constants were calculated to be 105.26mg·L-1 and 1250mg·L-1, and saturated adsorptive capacity were ]8.02mg·g-1 and "/3.50mg·g-1, respectively.The results of IR demonstrated the formation of MIPs.关键词
