  • 摘要: 2,4-二氯酚、2,4,6-三氯酚、五氯酚是氯酚类污染物的典型代表,鉴于其对人类身体健康的危害和对环境所造成的污染,已被很多国家列为环境优先控制污染物。研究粉末活性炭(PAC)对该3种氯酚的吸附过程以及投炭量、pH值和水质对PAC吸附性能的影响。结果表明:粉末活性炭可以有效去除水中的80%以上的氯酚;吸附行为符合Freundlich吸附等温线和Langmuir吸附等温线;以分子状态存在的氯酚比电离状态更容易被活性炭所吸附。
    Abstract: 2,4-dichlorophenol, 2,4,6-trichlorophenol, and pentachlorophenol are typical representatives of chlorophenols. As chlorophenols have caused great harm to human health and the environment, they are classified as environmental priority pollutants in many countries. The adsorption of these chlorophenols onto powdered activated carbon (PAC) was studied, with a focus on the effects of PAC dosage, pH, and water quality on adsorption performance. The results indicated that more than 80% of the chlorophenols could be adsorbed by PAC, which follows the Freundlich and Langmuir adsorption isotherms. Particularly, chlorophenols in the molecular state were adsorbed more easily by PAC than those in the ionized state.
