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 ad...
