Abstract

The radiation-induced decomposition of Na²SO⁴, Na² SO⁴10H²0, MgSO⁴7H²O, ZnSO⁴6H²O, CuSO²5H²O, Cr²SO⁴15H²0, Cr²SO4 aq., NiSO⁴6H²0, MnSO⁴H²0 and CoSO⁴7H²0 has been studied. Oxidation of the cation occurs only in NiSO⁴6H²0 and MnSO⁴H²0. Reduction of the SO⁴⁻⁻ occurs only in NiSO⁴6H²0. The remaining sulfate hydrates decompose to yield H² and O² only in very low yields. A mechanism is given to explain the observed results.
