The objective of this study is to explore the possibility of using waste cotton fabrics (WCFs) as low cost feedstock for the production of value-added products. Our previous study (Tian et al., 2014) demonstrated that acidic ionic liquids (ILs) can be highly efficient catalysts for controllable synthesis of cellulose acetate (CA) due to their dual function of swelling and catalyzing. In this study,...
In this work, the carboxylate-functionalized cellulose (CFC) from waste cotton fabrics (WCF) was studied for removal of cationic dyes from aqueous solutions. Instead of using conventional process for esterifying cellulose, which uses sulfuric or perchloric acid as catalysts, and methylene chloride as solvent, a novel mechanochemical approach which requires no catalyst or solvent in the reaction mixture...
