摘要
对邻苯二甲酸二甲酯在内蒙古粘土中的吸附特征进行了研究,并观察了pH值和离子强度等因素对吸附作用的影响.结果表明,邻苯二甲酸二甲酯在内蒙古粘土中的吸附符合一级动力学方程和Langmuir等温式,其吸附量随pH值的减小和离子强度的增加明显减小.
The adsorption of dimethyl phthalate in the soil is studied,and the influence of some factors, such as pH value and ionic strength on the adsorption is investigated. The result indicates that the process of adsorption conforms to the rule of first order kinetics mode and the Langmuir isotherm for the adsorption of dimethyl phthalate. The reduction of pH or the rise of the ionic strength can weaken the adsorption.
