Ion exchange and sorption on shungite are studied. The results demonstrate that this mineral is capable of sorbing both inorganic cations and anions. Cation exchange predominates in alkaline solutions, and anion exchange, in acidified solutions. Organic acids are sorbed substantially better; the sorption of aromatic acids by shungite is selective.
