Abstract: | Physicochemical properties of nanoporous modified carbon sorbents and sorption of cadmium ions (0.1–20 mg L?1) onto them from nitrate solutions at pH 5–7 were studied. The acid-base nature of functional oxygen-containing groups on the carbon surface of the sorbents was determined. The ability to sorb cadmium ions depends on the kind of chemical modification of the sorbent surface. |
