Abstract: Microgcls arc highly potcntial in the applications of rcmoval of heavy metal ions, bccausc of
thcir abundant functional groups and fast adsorption ratcs with heavy mctal ions. In this papcr, thc
progress in development of microgels for adsorption of heavy melal 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 mctal 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 Pb selectivity because the B18C6 units can specificall
apture Pb"to form stable B18C6/Pb"Host-guest complexes. The performance, advantages, and
applications of the threc types of microgels for adsorption of heavy mctal ions havc bccn discusscd
This review points out the three types of microgels are appropriate for adsorption of heavy metal ions
on different occasions
