Abstract

The disclosure provides a modified cyclodextrin/mesoporous silica for adsorbing Pb and Cd and application thereof, belonging to the technical field of adsorbent materials. By using surface modification, chloroacetic acid is used as anions, and a modified cyclodextrin is grafted onto a surface of a cyclodextrin/mesoporous silica by nucleophilic substitution to prepare the modified cyclodextrin/mesoporous silica adsorbent material. The modified cyclodextrin/mesoporous silica adsorbent material prepared in the disclosure has the advantages of simple preparation method, strong adsorbability, easy separation, good biocompatibility and the like. When the material is used as an adsorbent to adsorb heavy metal ions Pband Cd, maximum removal rates can reach 97.8% and 81.29% respectively. Therefore, the material has wide application prospects in removal of heavy metals in sewage and the like, thereby improving the water environment that people depend on for survival.
