摘　　要：分别在静态和动态条件下研究了Friedel-Crafs后交联型聚苯乙烯-二乙烯基苯 (St-DVB) 大孔吸附树脂对水溶液中多种低级一元醇的吸附性能,测定静态吸附等温线和动态吸附曲线,并分别按照Langmuir和Freundlich模型进行拟合。结果显示,树脂对水中低浓度低级一元醇的吸附过程属于放热的物理吸附过程,树脂吸附能力随着一元醇碳原子数的增加,即分子内疏水基团质量的增加而增加;树脂对直链醇的吸附能力稍强于同分异构的支链醇。under the static and dynamic conditions the adsorption properties have been studied for adsorpting low carbon alcohols in aqueous solution with Friedel-Crafs back-crosslinked St-DVB macroporous adsorbents XDA-1. Menstruate the adsorption isotherms in different temperature and calculate the data according to Langmuir and Freundlich equations. The results showed that the adsorption for low carbon unitary alcohols on XDA-1 proved to be an physical exothermic process. The adsorption ability of resins enhance with the increase of carbon number in unitary alcohols or the mass of hate water part in the molecule; When with the same number of carbon atomy., the ability of adsorption of line carbon alcohols is better than the alcohols with branch.
