Radiochemistry Aims and scope

Abstract

Granulated sorbents for recovery of cobalt radionuclides were prepared from carbonate natural raw material (dolomite) using thermal activation. The chemical and phase composition and the main physicochemical properties of the sorbents were determined. Their ability to sorb 60Co under dynamic conditions was evaluated. Among all the tested samples, the sorbent prepared at 900°C exhibits the best sorption and service characteristics (degree of recovery 0.8–1.0, distribution coefficient 1.7 × 103 ml g−1, total absorbed specific activity 7.7 × 104 Bq g−1).
