摘要
本文对四种不同酚类化合物在水体颗粒物上的吸附行为进行了实验研究.通过对三种不同形式的吸附等温线的比较,选择出最符合酚类化合物的Freundlich等温线,同时还观察了pH值和离子强度等因素对吸附的影响,并讨论了化合物的化学结构与吸附之间的关系.
The adsorption of four kinds of phenolic (phenol, o-chlorophenol, 2,4-dichlorophe-nol and pentachlorophenol) compounds on suspended particulate was examined in this study. Freundlich isotherm was suggested as the most appropriate type for these compound by comparing three different equations. The results showed sorption constants of phenol, o-chlorophenol, 2,4-dichlorophenol and pentachlorophenol are 0. 65,7.75, 11.56 and 47.16 respectively. The influence of some factors such as pH value and ionic strength on the adsorption was investigated and the relationship between the chemical structure of compounds and adsorption was also discussed.
