菜籽秆预处理废液再生木质素对镉铅离子的吸附性能
Adsorption of cadmium and lead ions onto regenerated lignin from pretreatment liquid of rapeseed stalk
摘要
Abstract
Acid-insoluble lignin solids were regenerated from the organic-acid pretreatment waste liquor of rapeseed stalk and were used for the adsorption of cadmium and lead ions from the artificial waste liquor. The influence of regeneration strategy, crystallinity, surface area and functional group content on the adsorption efficiency were studied in this paper. The results indicated that these two types regenerated lignins can effectively adsorb Cd2+, Pb2+ ions from artificial waste liquor and the content of functional group plays an key factor. In addition, the adsorbability of both two types of lignins is larger for Cd2+ ions than for Pb2+ ions.关键词
