Abstract
Equilibrium and metastable solid solutions of binary mixtures of BaSO4−CaSO4 and SrSO4−CaSO4, and sorbents based on mixtures of compounds in the systems BaSO4−MgSO4 and SrSO4−MgSO4 were prepared by special heat treatments. The sorption properties of such systems were studied in relation to their structural characteristics. A positive effect of the dynamic reconstruction of the lattice on the sorption of strontium ions was found in all cases. Good sorption properties were found for the systems BaSO4−CaSO4 and BaSO4−MgSO4 An effort was made to explain the mechanism of sorption on such systems, using several independent methods.
Abstract
The process of incorporation of radioactive wastes into a suitable matrix to form a stable product for long term disposal has been studied. The changes, occuring during the thermal treatment with glassy materials, i.e. drying, transformation processes, sintering, melting, etc. have been followed using emanation (radon) thermal analysis. This method was found useful in solving the problems of process development.
