Abstract

Physicochemical properties inherent in chitosan-containing solutions as well as the sorption properties of carbon materials modified with chitosan were studied. It has been found that the composites obtained exhibit anion-exchange properties. The chitosan-containing materials have been shown to exhibit a sufficiently high sorption capacity, which makes them efficient as sorbents for the concentration and extraction of gold, and other heavy and radioactive metals in the future.
