The Adsorption Behavior of Polyasparate Hydrogels to Zn~(2+)

The polyaspartate hydrogels was synthesized with the polysuccinimide as raw material and glutaraldehyde as cross-linking agent.The adsorption performance of polyaspartate hydrogels on Zn2+ was investigated.The result showed that adsorption of polyaspartate hydrogels on Zn2+ fit the Langmuir adsorption isotherm equation,and the adsorption was an endothermic process,and the polyaspartate hydrogels had greater adsorption capacity on Zn2+.
