In order to improve adsorption capacity of granular activated carbon (GAC), potassium permanganate was used to react with GAC to change the surface properties and improve the adsorption capacity of GAC. By batch experiments, im provement of adsorption capacity of potassium permanganate modified GAC (GAC M ) was studied. The influence of adsorption time, temperature, ratio of phenol with GAC/GAC M , initial concentration of phenol and pH on adsorption efficiency of GAC M was studied. The results showed that modified by potassium permanganate, the adsorption capacity of GAC improved to a higher level. The removal efficiency of phenol increased to about 20%.
