摘要
对苯酚在内蒙古粘土上的吸附进行了研究,测定了吸附等温线和吸附动力学,观察了pH值和离子强度等因素对吸附量的影响.结果表明:苯酚的吸附速率符合一级动力学规律;苯酚的吸附等温线符合Langmuir等温式,降低pH值和增加离子强度使苯酚在该土壤上的吸附量明显减小.
The adsorption of phenol on Inner Mongolia soil is studied. The adsorption isotherm and kinetics model for the adsorption procedure of phenol are determined. Langmuir isotherm and first order kinetics model are suggested as the most appropriate types for this procedure. The influence of some factors, such as pH value and ionic strength, on the adsorption is investigated, and the results show that the reduction of pH value or the rise of ionic strength can weaken the adsorption.
