Area of Science:

  • Environmental Science
  • Materials Science
  • Chemical Engineering

Background:

  • Azo dyes like methyl orange cause significant environmental pollution.
  • Effective and eco-friendly adsorbents for dye removal are lacking.
  • Shell resources are underutilized and contribute to waste.

Purpose of the Study:

  • To develop economical and eco-friendly magnetic adsorbents from shell waste.
  • To investigate the adsorption of methyl orange using these novel adsorbents.
  • To explore the potential for high-value utilization of shell resources.

Main Methods:

  • Sol-gel and hydrothermal synthesis methods were employed.
  • Magnetic hydroxyapatite microspheres (Fe3O4@SiO2/HAP) were synthesized.
  • Adsorption experiments were conducted to evaluate methyl orange removal efficiency.

Main Results:

  • Adsorption capacities reached up to 94.48% and 88.94% for methyl orange under acidic conditions (pH=4).
  • Adsorption followed Freundlich isotherm and pseudo-second-order kinetics, indicating a spontaneous, exothermic process.
  • The adsorbent demonstrated good recyclability and performance.

Conclusions:

  • Shell-based magnetic hydroxyapatite microspheres are effective for methyl orange removal.
  • This method offers a sustainable pathway for waste shell utilization and dye pollution mitigation.
  • The findings provide new strategies for managing acid dye wastewater and shell waste.
