The water-absorbing resin or high elastic gel is a type of new functional polymer materials. It has excellent absorbency and water-retention properties

and is widely used in the personal care and hygienic products

etc. but is hardly applied in the adsorption and separation materials. Based on the introduction to the basis types and their major characters

the affecting factors of the absorbency for the water-absorbing resin

the structure and its behavior

the adsorption behavior for heavy metal ions

the coordinating atoms or groups and ligand-ligand interaction

the affecting factors of adsorption process for the water-absorbing resin are reviewed. And then a few proposes are presented for application of adsorption for the water-absorbing resin.
