Chromatographic separation of inorganic ions on specially prepared calcium sulphate sticks

It has been shown⁶ that specially prepared calcium sulphate sticks are suitable as adsorbent bodies in the chromatographic separation of inorganic ions. With the help of these sticks separations of Cu⁺² — Sb⁺³, Bi⁺³ — Sb⁺³, Cd⁺² — Sb⁺³, Cd⁺² — Sn⁺², Hg⁺² — AS⁺³, Hg⁺² — Sb⁺³, Cu⁺² — As⁺³, Bi⁺³ — As⁺³, Hg⁺² — Cu⁺², Cu⁺² — Fe⁺³ have been effected.
