Fluorescence emission behavior of Eu(III) sorbed on calcium silicate hydrates as a secondary mineral formed without drying process
Autor: Yuichi NIIBORI, Masayuki NARITA, Akira KIRISHIMA, Taiji CHIDA, Hitoshi MIMURA
Publikováno v: Mechanical Engineering Journal, Vol 1, Iss 4, Pp TEP0027-TEP0027 (2014)
Calcium silicate hydrate (CSH) is a main component of cement-based material required for constructing the geological repository. As in many countries, since the repository in Japan is constructed below water table, we must consider the interaction of

Preparation and characterization of tri-n-octylamine microcapsule (TOA-MC) used for selective separation of Re(VII) [chemical analogs of Tc(VII)] in the high level liquid radioactive waste (HLLW)
Autor: Tsuey Lin Tsai, Shih Chin Tsai, Chuan Pin Lee, Hitoshi Mimura
Publikováno v: Journal of Radioanalytical and Nuclear Chemistry. 319:1235-1242
TOA-MC was developed to act as absorbent for selective separation of 99Tc(VII) from high-level radioactive liquid waste. The uptake (%) of Re(VII) a substitute for Tc(VII) due to similar chemical behavior by TOA-MC normally exceeding 95% in the prese

Stable Solidification of Silica-based Ammonium Molybdophosphate in Ceramic Matrices and Its Cesium-leaching Properties
Autor: Mingliang Xu, Yan Wu, Yuezhou Wei, Hitoshi Mimura
Publikováno v: Chemistry Letters. 47:179-182
A pressing/sintering method was used for the stable solidification of spent cesium adsorbent by adding natural allophane and mordenite. The stable Cs4Al4Si20O48 crystalline phase was recrystallized by the reaction of Cs2O, Al2O3, and SiO2 above 1000

Stable solidification of silica-based ammonium molybdophosphate by allophane: Application to treatment of radioactive cesium in secondary solid wastes generated from fukushima
Autor: Yuezhou Wei, Hitoshi Mimura, Chuan Pin Lee, Yan Wu, Xiaoxia Zhang
Publikováno v: Journal of Hazardous Materials. 341:46-54
Silica-based ammonium molybdophosphate (AMP/SiO2) is an absorbent material that can effectively remove Cs from radioactive-contaminated wastewater (RCW) generated by Fukushima nuclide accident. Pressing/sintering method was used for final disposal of

Development of adsorption and solidification process for decontamination of Cs-contaminated radioactive water in Fukushima through silica-based AMP hybrid adsorbent
Autor: Hitoshi Mimura, Xiaoxia Zhang, Yan Wu, Yuezhou Wei
Publikováno v: Separation and Purification Technology. 181:76-84
Developing highly efficient cesium (Cs) adsorbent and a stable solidification method for Cs is vital for the advancement of the decontamination system for Fukushima Daiichi Nuclear Power Plant. A novel porous silica loaded with ammonium molybdophosph
