Overview

This research demonstrates effective phenol removal in aqueous solution using activated carbon made from Catha edulis, indicating its potential in water treatment.

Key Points

  • The activated carbon from Catha edulis stems achieved a phenol removal efficiency of 99.9% under optimized conditions.
  • Characterization showed a high surface area of 1323 m2/g and a porous structure suitable for adsorption applications.
  • Adsorption followed the Langmuir model and pseudo-second-order kinetics, confirming the effectiveness of the material.
  • Batch experiments employed a full factorial design, testing 16 conditions to determine optimal phenol removal parameters.
