摘要

Natural cellulose and oxycellulose are heterogeneous highly hydrated substances. They have the same chemical composition, but different size of molecules and representation of COOH groups organized into complex supramolecular structure. The oxycellulosic adsorption capacity of organic cationic dyes increases with increasing -COOH group content and distinctly increases with other competitive ions in the aqueous solution.
