Adsorption of Powdered Activated Carbon on Simulative p-Aminophenol Wastewater

The adsorption effect of activated carbon on simulative p-aminophenol wastewater was investigated under static conditions.The influences of the factors,such as the pH value of wastewater,the dosage of activated carbon,the oscillation time,wastewater temperature,the concentration of p-aminophenol,the oscillation velocity and the salt,on adsorption effect were confirmed.The optimum conditions for the 100 mL simulative p-aminophenol wastewater with concentration of 50mg/L were follow:pH=6.4,the dosage of activated carbon of 4.5g,wastewater temperature of 35℃,the oscillation time of 2.5h.
