粉末活性炭吸附对氨基苯酚模拟废水的效果

Adsorption of Powdered Activated Carbon on Simulative p-Aminophenol Wastewater

在静态条件下,研究了活性炭吸附对氨基苯酚模拟废水的效果,确定了处理废水的pH值、活性炭用量、振荡时间、温度、废水中对氨基苯酚浓度、振荡速率以及电解质对吸附效果的影响.实验表明:活性炭在pH值为6.4,用量4.5g,温度35℃,振荡2.5h的条件下,对100mL质量浓度为50m g/L的对氨基苯酚模拟废水处理效果最佳。

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.
