The absorbents including MnO2, fly ash, NaY zeolite and activated carbon powder were used to study the adsorption capacity of phenol. The effect of contact time and dosage of absorbents on the removal efficiency were investigated. The experimental results suggested that activated carbon powder is most effective absorbent, following as fly ash, MnO2 and NaY zeolite which the removal efficiency could reached 98.41%,77.65%, 60.19% and 24.13% at 90min respectively. The data indicated that the activated carbon powder was favorable for adsorption while NaY zeolite was unfit for absorbent of phenol from aqueous solution due to lower removal.
