Preparation and Adsorption Performance of Nano-hydroxyapatite-Enhanced Acrylamide Hydrogel Adsorbent
Year: 2022
Type: article
Abstract: In this study, a hydrogel adsorbent was successfully synthesized using hydroxyapatite/acrylamide/β-cyclodextrin to adsorb heavy metal ions and dyes in water. In the study, different contents of hydroxyapatite were added to the hydrogel, and then the mechanical properties and adsorption properties of the material were studied. The results show that the compressive strength of hydrogel added with hydroxyapatite increased by 37.1%. According to the adsorption isotherm model, the maximum adsorption capacity is 300mg/g. In addition, the preparation process of the composite hydrogel is simple, and can be used at a lower pH value, and can be used multiple times. Therefore, the material is of great significance to the treatment of pollutants.
