| 摘 要： | 研究了松花江3个不同采样点沉积物对水体中苯酚的吸附行为,初步探讨了沉积物的有机质含量、颗粒粒径及水体pH对吸附作用的影响.结果表明:苯酚在松花江沉积物上的吸附行为可以同时用Freundlich型和Langmuir型吸附等温式来描述,说明其吸附行为比较复杂.吸附量随沉积物中有机质含量的升高而增大,随沉积物颗粒粒径的增大而减小,随水体pH的升高而增大.

| Abstract: | The adsorption of phenol on three different sediment samples in Songhua River was studied.The effects of the organic matter content of the sediments,particle size and pH value on the adsorption were also studied preliminarily.The results showed that the adsorption behaviors of phenol on Songhua River sediment can be well described by Freundlich and Langmuir adsorption isotherm equations,that means its adsorption mechanism are quite complex.The Adsorptive capacity increases with the increase of pH value and organic content in sediments,decreases with the increase of particle size. |
