Journal AWWA - Technical Note: Adsorption of p-Dichlorobenzene From Water AWWA期刊-技术说明:从水中吸附对二氯苯
发布日期: 1984-02-01
本文介绍了对二氯苯(PDB)在背景腐殖酸存在下单独吸附的速率和平衡现象的系统研究结果。PDB是一种有毒化合物,已在饮用水和地下水中检测到,并被列入优先污染物清单。密歇根吸附设计和应用模型(MADA)用于模拟和预测PDB在近似于水处理实践中遇到的条件下的吸附。结果表明,活性炭吸附可能为去除PDB和类似化合物提供一种有吸引力的方法。此外,活性炭去除PDB的效果似乎不会受到腐殖酸等背景有机物的不利影响。 碳对PDB的吸附似乎很容易可逆,这表明从溶液中吸收PDB主要是因为范德华引力相对较弱。此外,MADAM模型通常能够模拟和预测固定床吸附器去除PDB的性能。包括9个参考文献、图表。
This article describes the results of a systematic study of rate and equilibrium phenomena associated with the adsorption of p-dichlorobenzene (PDB) individually and in the presence of background humic acids. A toxic compound, PDB has been detected in drinking waters and groundwaters and is included in the list of priority pollutants. The Michigan Adsorption Design and Applications Model (MADAM) is used for simulation and prediction of PDB adsorption under conditions approximating those encountered in water treatment practice. Results suggest that activated carbon adsorption may offer an attractive means for removal of PDB and similar compounds. Furthermore,the effectiveness of activated carbon for PDB removal appears not to be adversely affected by background organics such as humic acids. PDB adsorption by carbon appears readily reversible, suggesting that uptake from solution occurs primarily because of relatively weak van der Waals' attraction forces. In addition, the MADAM model was generally able to simulate and predict the performance of fixed-bed adsorbers for removal of PDB. Includes 9 references, figures.
