Study on disposing phenol-containing wastewater by trivalent chromium ion modified bentonite
The optimal conditions of adsorbing phenol by trivalent chromium ion modified bentonite are studied. The results show that the adsorption efficiency is satisfactory, and the adsorption equilibrium can be reached quickly. The alkali conditions are helpful to adsorb. The best result of phenol removing rate is over 83%, and the phenol content in treated water is less than the third discharging level in the national standard.
