Abstract

By means of microwave radiation, hydroxy-Aluminum modified bentonite adsorbent has been prepared. The influential factors of modified bentonite on the adsorbent capacity of phosphor in wastewater are studied. The results show that when Al/bentonite ratio is 6 mmol/g, microwave power 480 W, and microwave radiation time 8 min, the adsorption efficiency of phosphor is very good. When pH is 7, at normal temperature and modified bentonite dosage 6 mg/L, reaction time 15 min, the removal rate of phosphor from the wastewater whose phosphor concentration is 50 mg/L reaches 97.3%.
