Study on Adsorption of Cr(VI) in Wastewater by Powdered Activated Carbon

This research focuses on absorption of Cr(VI) in wastewater by powdered activated carbon, and determines the effect of pH, initial concentration of solution, amount of powdered activated carbon, adsorption time, adsorption temperature, etc, on adsorption of Cr(VI) in wastewater. The results show that the treatment of 100mL containing Cr(VI) wastewater with concentration of 50mg/L will work best in the conditions of 0.35g powdered activated carbon, pH=3.0, 298K, and 1hour oscillatory adsorption.
