为了解香蒲绒纤维对油的吸附性能与机理,通过静态实验,研究了吸附时间、温度、香蒲绒投加量、油浓度对狭叶香蒲绒吸附水溶液中0~#柴油、菜籽油的影响。香蒲绒纤维对油的吸附大约15 min达到平衡;2种油类物质的吸附量随温度、香蒲绒投加量增加而降低,随0~#柴油和菜籽油含量增加而增加。热力学分析表明,香蒲绒对油类物质的吸附过程自发而且放热;拟二级动力学模型比拟一级动力学模型对吸附动力学实验结果拟合度更高;相比Freundlich等模型,0~#柴油和菜籽油的平衡吸附量与Langmuir吸附等温模型的拟合效果更好;25 ℃条件下,由Langmuir线性模型得到的0~#柴油和菜籽油的最大吸附量Q_m分别为32.15 g/g和34...

To understand the characteristics and mechanism of the adsorption of oil on cattail fiber, the effects of sorption time, temperature, dose of cattail fiber, and concentration of oil on the sorption of zero diesel and colza oil from aqueous solution were investigated. It took about 15 min to reach adsorption equilibrium; the adsorption capacity of both oils decreased with temperature and cattail fiber dose, and increased with the concentration of the oils. The adsorption process was spontaneous and endothermic, and was well depicted by the pseud...
