| Abstract: | The microcystins molecularly imprinted polymers（MIPs）were synthesized by bulk polymeriza- tion 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±1.2 × 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. |
