| Abstract: | 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＋. |
