摘要
研究了邻硝基苯酚、五氯苯酚、2,4-二氯苯酚和2,4-二硝基苯酚等酚类化合物在黄河水体沉积物上的竞争吸附行为。结果表明,水-沉积物体系中,当两种以上的酚类化合物同时存在时,可以产生竞争吸附,竞争吸附能力由该种化合物的吸附能力和吸附速率大小决定,吸附能力和吸附速率大的酚类化合物在水体沉积物中具有较大的竞争吸附能力。
In this paper,the competitive adsorption behavior of o-nitrophenol,pentachlorophenol,2,4-dichlorophenol and 2,4-dinitrophenol on the Yellow River sediments was studied.The results showed that competitive adsorption occured when two or more of the four phenolic compounds exist in the water-sediment system.The competitive adsorption capacity depends mainly on adsorbability and adsorption rate of each phenolic compound and phenolic compounds with high adsorbability and adsorption rate have greater competitive adsorption capacity.
