Abstract (en)
[origin: WO2011061399A1] The present invention relates to oxidized lignin-containing materials and derivates thereof and their uses. In particular, the invention relates to oxidized lignin-containing materials capable of sorbing positively charged components, such as metal ions, from aqueous fluids, such as industrial effluents. The present invention further provides a method for purifying an aqueous fluid containing charged components and a method for purifying solids permeable to aqueous fluid, said solids containing charged components.
