Synthesis of γ-AlOOH Nanosheets and Their Adsorption Properties for Heavy Metal Ions

Year: 2025

Type: article

Abstract: The lamellar γ-AlOOH nanosheets were rapidly synthesized by high temperature liquid salt as a reaction medium. The micromorphology, crystal structure, and surface valence characteristics of the samples were characterized by XRD, SEM, TEM, BET, and XPS. The results show that the γ-AlOOH nanosheets have a typical layered structure and a large specific surface area. Taking Cu2+ as the target heavy metal ion pollutant, the adsorption properties of γ-AlOOH nanosheets have been studied. The results show that γ-AlOOH nanosheets have excellent adsorption properties of Cu2+ at pH = 5, and the adsorption capacity is up to 141.1 mg/g, which has potential of applications as heavy metal ion adsorbent for industrial wastewater.
