摘要

通过聚乙烯亚胺(PEI)中氨基和纤维素中羟基之间的戊二醛交联反应,合成了PEI接枝的多孔纤维素气凝胶,并研究其对废水中Cr(Ⅵ)的吸附性能。通过批量吸附实验系统考察了体系pH、吸附时间和初始浓度等相关因素对吸附量的影响。

Abstract

Polyethylenimine (PEI) grafted cellulose aerogels,namely cellulose@PEI,were synthesized through a glutaraldehyde crosslinking reaction between the amine groups of PEI and the hydroxyl groups of cellulose.The prepared materials were investigated for the removal of Cr(Ⅵ).The effects of pH,adsorption time,initial concentration and other factors on adsorption capacity were studied by batch adsorption experiments.
