Description
Summary:Cesium removal is a major priority of radwaste treatment process. A great number of synthetic ion enchanters have been prepared during the last forty years. However, few ion enchanters have the capability to effectively separate cesium isotopes from the high sodium-concentration, highly alkaline solutions. Texas A&M University and Sandia National Laboratories have synthesized two crystalline silico-titanates, named TAM-5 and MTAM-5. TAM-5 and MTAM-5 have very high cesium selectivity in a broad range of sodium and alkaline concentrations and are stable under high radiation exposure. In this study, the effects of various factors on the TAM-5 and MTAM-5 syntheses were studied. TAM-5 and MTAM-5 synthesis were optimized and scaled up to one and five gallon autoclaves, respectively. The mechanism and the kinetics of MTAM-5 synthesis were determined and an autocatalytic reaction model which successfully descries the kinetics of the synthesis was developed. The synthesis of organic free TAM-5 and MTAM-5 were also investigated.
