Summary, etc. The effect of four different parameters such as <em>p</em>H, initial phenol concentration, adsorbent dose and temperature on the adsorptive removal of phenol from aqueous solution over commercial granular activated carbon (GAC) has been studied. Two-level full factorial design (FFD) combined with response surface methodology (RSM) have applied to find the best operating conditions. The optimum <em>p</em>H, initial phenol concentration, adsorbent dose and temperature have been found by applying desirability function (DF) to be 6, 1000 mg/L, 3 g and 28.75°C. The granular activated carbon has been characterized using different physicochemical methods. The experimental data best fits in Freundlich isotherm Equation and the removal follow pseudo-first-order kinetics. Thermodynamic parameter reveals that the removal process is feasible, exothermic and spontaneous in nature. The adsorbent is regenerated with 0.1 M NaOH solution for further reuse.
