| 摘 要： | 研究了振荡时间、温度、pH、腐殖酸添加量等因素对两种类型活性炭PJ-20、ZJ-15吸附微污染水源水中微量2,4-二氯苯酚效应的影响,同时对吸附等温进行Langmuir方程、Freundlich公式和BET公式曲线拟合.结果表明:PJ-20型活性炭对2,4-二氯苯酚的吸附效果稍好于ZJ-15型,温度有利于活性炭对2,4-二氯苯酚的吸附,pH值应控制在小于8的范围内,腐殖酸添加量对吸附效果也有一定的影响.

| Abstract: | GAC was used as absorbent of 2,4-dichlorophenol in micropolluted water sources and the effects of shaking time,pH,the temperature and humic acids quantity on the adsorption efficiency were studied.The results were described by Langmuir,Freundlich and BET models.The results showed that the adsorptive efficiency of 2,4-dichlorophenol on GAC(PJ-20) was a little better than GAC(ZJ-15).The higher temperature was of great benefit to the adsorption and the adsorptive capacity was higher in the lower pH.Humic acids quantity had certain influence on the 2,4-dichlorophenol removal efficiency. |
