| 中文摘要 |
| 通过静态吸附实验,探讨了亲水性的苯酚(Ar-OH)和亲脂性的对氯苯酚(p-chl),在白洋淀地区水陆交错带-芦苇地中的天然颗粒物上的吸附规律。对于亲水性有机物,它在颗粒物上的吸附符合Langmuir等温吸附,平衡浓度ce的对数与吸附率q的对数呈直线关系;而亲脂性有机物的吸附则符合Linear吸附关系,即平衡浓度ce1与吸附率q1之间呈直线关系,且吸附量明显高于亲水性的有机物。 |
| 英文摘要 |
| The adsorption rule of solvophobic phenol and hydrophobic p-chlorophenol in Bat Yang Dian land/inland ecotones was studied by using batch equilibrium method. For solvophobic organics, the adsorption rules follow the Langmuir type equation, and there is a linear relationship between the logarithm of equilibrium concentration ce and adsorption coefficient q; but for hydrophobio organics,the relationship between equilibrium concentration ce1 and adsorption coefficient q1 follows the Linear-type equation, and adsorption amount is higher than that the hydrophobic organic does. |
