Summary:In this paper the reagent properties of aqueous extracts from crushed oak bark sawdust to copper ions were investigated. The bark currently does not find practical application. For the experiment, the bark was pre-mechanically activated. The extracts were obtained by leaching sawdust with distilled water and an aqueous solution of alkali by boiling for 1 hour at a ratio of 1:10, respectively, for the most complete extraction of the organic component into the aqueous medium. Purification with extracts was carried out with model solutions with the concentration of ions Cu2+ = 164.3 mg/dm3 at pH = 2.5; 4.0; 6.0 and 9.0 to determine the most efficient removal of copper ions. Testing of the purification process was carried out at different ratios of the volume of the model solution and extracts of oak bark. A mechanism for the removal of copper ions from solution is proposed.
