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 the mechanical properties and adsorption properties of the material were studied. Results showed that the compressive strength of the hydrogel added with hydroxyapatite increased by 37.1%. The adsorption isotherm model demonstrated that the maximum adsorption capacity was 300 mg/g. In addition, the preparation process of the composite hydrogel was simple and could be used at a low pH for multiple times. Therefore, the material is of great significance to the treatment of pollutants.
