To the question of obtaining activated coals from plant raw materials of the Republic of Dagestan
Texture and sorption properties of activated carbons obtained from peach wood with respect to Rb+, Cs+, Cu2+ ions were studied. The influence of the concentration of phosphoric acid used in the activation of the feedstock, as well as the heat treatment mode on the value of the specific surface and the specific volume of micropores is established. The research has shown that the sorption activity of activated carbon from the wood of a peach tree, obtained in the "shock" mode, has a high selectivity to rubidium ions.
