Structure Formation in the Ceramic Matrices for Immobilization of Wastes Substances

The paper studies processes of structure formation at heat treatment of purification wastes of radioactive cesium waters using sorbents based on clay minerals and zeolite. We define structural and mechanical properties of simples and find the optimum conditions of their heat treatment aimed at obtaining based on crystalline structures with the most effective physical and mechanical properties. We also investigate mechanical and chemical stability of ceramic matrices formation and also strength of commitment 137 Cs in them.

Sorption-reducing treatment of groundwater from uranium compounds

The paper considers the processes of sorptionreducing treatment of water polluted with uranium compounds by various active agents. Our research subject is groundwater selected from the hole near the tailing dump of waste of uranium ore processing from the East ore-dressing and processing enterprise situated near Zhovti Vody. To that end, we utilize the activated sludge of Bortnytska aeration station and Fe0 iron powder as active agents.
