Overview

Demonstrates effective copper ion removal in water using hydroxyapatite microspheres, suggesting a sustainable solution.

Key Points

  • The research aims to develop an efficient and eco-friendly adsorbent to remove copper ions from water effectively.
  • Synthesis of hydroxyapatite porous microspheres via a hydrothermal method.
  • Conducting adsorption experiments to measure copper ion removal capacity.
  • Characterization of the adsorbed material using XRD, FTIR, and XPS to determine adsorption mechanisms.
  • Analysis of various factors influencing adsorption performance, including pH and temperature.
  • Maximum adsorption capacity of hydroxyapatite microspheres is 116 mg/g for copper ions.
  • Adsorption follows pseudo-second-order kinetics and Sips isotherm model with a high correlation coefficient of R2 = 0.9997.
  • Ion exchange is identified as the dominant mechanism of adsorption.
  • High specific surface area (207 m2/g) and favorable mesoporous structure contribute to effective copper ion diffusion and adsorption.
