| 摘 要： | 本文用批量平衡法研究－系列芳香族酮类化合物在东北黑土中的吸附，采用Ｆｒｅ－ｎｕｎｄｌｉｃｈ吸附等温方程求得土壤吸附常数（ｋｆ），研究表明：１２种芳香族酮类化合物的吸附等温线有线性和非线性两种形式，对化合物的土壤有机碳吸附常数（ｌｇＫｏｃ）进行定量结构－性质（ＱＳＰＲ）分析，发现芳香族酮类化合物的土壤有机碳吸附常数与正辛醇／水分配系数相关不显著，土壤有机碳吸附常数与分子极化率（ａ）有较好的相关性，这

| Abstract: | The sorption of 12 substituted aromatic ketone compounds by black soil from northeastern China was studied using batch equilibrium method. The data were fitted to the Frenundlich equation with the regression analysis. The results showed that the sorption behaviors of 12 substituted aromatic ketone compounds could be characterized by linear and non-linear isotherms suggesting different sorption mechanisms. A QSPR equation was established and indicated that molecular polarity was an potential factor affecting the organic carbon sorption coefficients of these 12 substituted aromatic ketones in soils. |
