The Research of Adsorption about Activity Al_2O_3 to Aniline in Wastewater

研究了活性Al2O3吸附废水中的苯胺的动力学性能,实验考察了吸附剂用量、吸附时间、温度、溶液酸碱度等方面在活性Al2O3吸附苯胺的影响,得出活性Al2O3的最佳使用条件,采用单孔模型对测定的吸附动力学数据进行拟合,确定了283k时的苯胺在活性Al2O3上的扩散系数。实验结果表明,Crank单孔模型可以很好地描述苯胺在活性Al2O3上的吸附过程。

The adsorption kinetics of aniline in wastewater by active Al2O3 was studied.The effect of adsorbent dosage,adsorbent time,temperature and solution pH on the aniline in wastewater by active Al2O3 were examined and the preparing conditions were optimized.From the adsorption kinetic data of aniline on active Al2O3,the Crank monopore model was used to fit the diffusion coefficients at 25℃ temperatures.The results proved that Crank monopore model could be used to describe the adsorption process of aniline on active Al2O3.
