| Abstract: | Microgels are highly potential in the applications of removal of heavy metal ions,because of their abundant functional groups and fast adsorption rates with heavy metal ions. In this paper,the progress in development of microgels for adsorption of heavy metal ions was reviewed,in particular,three types of microgels were introduced. The first type is microgels with multi-functional groups,such as carboxyl,amino,hydroxyl,mercapto,and sulfonate groups,which can adsorb heavy metal ions through electrostatic interactions between the multi-functional groups and heavy metal ions. The second type is ion-imprinted microgels,and the third type is microgels with benzo-18-crown-6 ether(B18C6)groups,which show excellent Pb2+ selectivity because the B18C6 units can specifically capture Pb2+ to form stable B18C6/Pb2+ host-guest complexes. The performance,advantages,and applications of the three types of microgels for adsorption of heavy metal ions have been discussed. This review points out the three types of microgels are appropriate for adsorption of heavy metal ions on different occasions. |
