摘    要:通过静态吸附实验,探讨了亲水性的苯酚和新脂性的对氯苯酚,在白洋淀地区水陆交错带-芦苇地中的天然颗粒物上的吸队规律。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。

关 键 词:有机污染物 颗粒物 吸附 水陆交错带 土壤

Abstract:he 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 c. 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.
Keywords:organic pollutants  particles  adsorption  Bat Yang Dian area   soil of land/inland eco tones.
