| Abstract: | The microcystins molecularly imprinted polymers(MIPs)were synthesized by bulk polymerization using microcystin(MC-LR) as the template,and the preparation process was optimized.The MIPs were characterized by electron microscopy,porosity analysis and FT-IR,and their reaction mechanism and adsorption performance were investigated.The results showed that the ratio of monomer,template,and crosslinking agent was 0.9×106∶1∶1.2×106,the adequate elution time was 25 min,and the maximum adsorption was 153.7 μg/g.The MIPs has a significant and specific adsorption to MC-LR. |
