摘要
通过批量平衡法实验，比较了作为有机碱离子化有机污染物之一的苯胺在酸性、天然水和碱性水体中悬浮颗粒物上的吸附特征，并观察了水体颗粒物中腐殖酸含量对苯胺吸附行为的影响。结果表明，苯胺在水体悬浮颗粒物上的吸附遵守Ｆｒｅ－ｕｎｄｌｉｃｈ方程：在ｐＨ５—１０范围内苯胺被吸附的能力随介质ｐＨ值和颗粒物中有机质含量的升高而增大．
Through batch equilibrium experiment method in lab,the adsorption character of aniline as one of the alkali ionizable organic pollutants on suspended particles in acidic,natural and basic simulated waters was compared,and the effect of humic acid content in the particles of water on aniline adsorption behavior was observed.The results show that the adsorption of aniline on suspended particles in the water accords with Freundlich equation;the capacity of aniline adsorption at the range of pH5_10 increases with incrasing of pH of water and organic matter content in particles.
