Modiifed bentonite was prepared by means of adsorbent from Aluminum-doped TiO2. Effects of TiO2 modiifer dosage, the amount of aluminous dope, microwave power, microwave time on phenol removal efifciency in wastewater were investigated. The experimental results showed that the best prepared conditions were TiO2 modiifer dosage of 14 mmol/10g, Aluminous-doped dosage of 2 mmol/10g, microwave power 260 W and microwave time 8min. Under the following conditions: pH value 8.5, modiifed bentonite dosage of 2 g/L, the removal rate of phenol will be up to 84% at a initial concentration of 200 mg/L in wastewater.
