Adsorption and partition of benzo(a)pyrene on solids with different particle size from the Yellow River;

苯并(a)芘在黄河水体不同粒径颗粒物上的表面吸附和分配(作用)特征

The contributions of adsorption and partition to the sorption of PAHs were investigated.

通过模拟实验研究了多环芳烃在黄河水体颗粒物上的吸附特征,重点探讨了表面吸附和分配(作用)对吸附的贡献,结果表明:①随着泥沙含量的增加,总吸附量在增加,而单位颗粒物的吸附量却在减少;且泥沙含量不同时,吸附等温式的拟合方程也不同;②颗粒物对多环芳烃的吸附等温线与吸附-分配复合模式拟合较好;表面吸附和分配(作用)对多环芳烃的吸附实验值与吸附-分配模式中的理论值比较吻合;③在实验浓度范围内,黄河颗粒物对多环芳烃的吸附以表面吸附为主,如当颗粒物含量为3、8和15g/L,液相平衡浓度分别为2。

The results indicated that the sediment-water partition coefficients K of aniline and p-nitrophenol increased when the initial concentrations were set at 200mg/L and 1200mg/L for SDBS.

结果表明2 0 0mg/L和 1 2 0 0mg/L的SDBS存在下 ,苯胺和对硝基苯酚的沉积物 水分配系数均增大 ,分配(作用)的增大倍数与有机物的KOW呈正相关 ;苯酚的分配系数则因表面活性剂存在浓度的不同分别增大和减小 。
