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.
