颗粒活性炭对挥发性有机气体的吸附研究

Study on Selective Adsorption of VOCs by Granular Activated Carbon

VOCs是指挥发性有机化合物,其对人体与环境造成了巨大的危害。本文旨在进一步研究影响活性炭吸附有机气体的因素及关系。比表面积是影响吸附性能的主要因素。吸附质的分子动力学直径正处于活性炭的有效吸附孔径时,吸附效率最好。活性炭表面官能团对不同吸附质产生的作用不同。

VOCs is the organic compound of command,which has caused great harm to human and environment.The factors and relationships of the organic gases adsorbed by activated carbon were further studied.The molecular dynamics of the adsorption is the best when the diameter of the molecular dynamics is in the active carbon,and the adsorption efficiency is the best.Activated carbon surface functional groups of carboxyl group on carbon tetrachloride,ethyl acetate,toluene,1,2 dichloro ethane,butanone inhibition and adsorption of methanol on a role in promoting.The effect of the different adsorption material is also different from the phenol hydroxyl group.
