Abstract	This study investigates the removal of textile dye from aqueous solutions using activated carbon prepared from mango peel waste. The adsorbent was synthesised by chemical activation with phosphoric acid and evaluated under varying experimental conditions including contact time, pH, dye concentration, and adsorbent dose. Batch experiments revealed that dye removal efficiency increased with time, reaching equilibrium within 90 minutes. The adsorption followed the pseudo-second-order kinetic model and conformed to the Langmuir isotherm, indicating monolayer adsorption on a homogeneous surface. The maximum adsorption capacity was found to be 64.25 mg/g. The results confirm the potential of mango peel-derived activated carbon as an economical and sustainable adsorbent for dye-laden wastewater treatment.
