Implication

Batch experiments show 96.9% phenol removal in water using mesoporous activated carbon, indicating effective pollution management.

Key Points

  • This research aims to optimize the adsorption of phenolic compounds using orange-peel-derived activated carbon.
  • Synthesized activated carbon via phosphoric acid activation at 400 °C for 60 min.
  • Optimized adsorption through response surface methodology considering various parameters.
  • Conducted thermodynamic analysis and batch experiments to assess adsorption efficiency.
  • Achieved 96.9% phenol removal under optimal conditions (pH 5, 150 min, 2 g L⁻¹, 10 µg L⁻¹).
  • Adsorption kinetics followed a pseudo-second-order model with R² = 0.995.
  • Maximum adsorption capacity fitted Langmuir isotherm, achieving 10.1 mg g⁻¹.
