Abstract

Hollow aluminosilicate microspheres (cenospheres) of stabilized composition (glass phase – 95.4 wt. %; (SiO2/Al2O3)glass – 3.1) isolated from fly ashes from coal combustion were used to prepare composite sorbents containing a sorption-active component based on zirconosilicates of framework structure. The synthesis products were characterized by XRD, SEM-EDS and low-temperature nitrogen adsorption methods, and their sorption properties towards Cs+ were studied. Zirconosilicate material demonstrates the high distribution coefficient in the process of Cs+ sorption from aqueous solutions (~103–104 ml/g) and stability of sorption capacity as a result of decationation. The possibility of application of SPS-synthesis technology to create high-density mineral-like ceramics for cesium immobilization based on the zirconosilicate sorbent has been investigated. The results of dilatometry, structure and porosity analyses were obtained for ceramics sintered at different temperatures (800–1000°C).
