有机污染物在白洋淀地区水陆交错带土壤颗粒物上的吸附

Adsorption of Organic Pollutants on Particles of Land/Inland Ecotones in Bat Yang Dian Area

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．

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.
