Abstract: The results of studying the processes of extraction of zinc ions from the solution with the help of a cellulose-containing sorbent (grain dust) are given. It has been determined that the sorption process of zinc ions from aqueous media by grain dust-based sorbents can be described using three dependencies: Freundlich adsorption equations (for equilibrium metal ion concentration ranges of 0,001–0,014 mol/dm3 and 0,015–0,0195 mol/dm3), Langmuir monomolecular adsorption (0,014–0,015 mol/dm3) and Brown, Emmet and Teller polymolecular adsorption (0,0195–0,0271 mol/dm3). It is shown that ionic exchange with participation of carboxyl and hydroxyl groups, as well as physical adsorption act as mechanisms for bonding zinc ions with grain dust samples.
