Preparation and Soxhlet leaching studies of strontium incorporated sodium iron titanate by ICP-OES and NAA methods.

For employing strontium incorporated sodium iron titanate (Sr-SIT) in applications related to aqueous environments, the assessment of leach resistance of constituent elements assumes significance. The sodium iron titanate was prepared by the conventional co-precipitation method, and an ion exchange method was adopted for introducing strontium. 28-day-long Soxhlet leaching studies were undertaken for irradiated and unirradiated sintered solid pellets of Sr-SIT. The leaching propensities of the Sr-SIT constituents were analyzed by ICP-OES and neutron activation analysis respectively, for the unirradiated and irradiated Sr-SIT. These studies established the chemical stability of Sr-SIT towards leaching. [ABSTRACT FROM AUTHOR]
