Leaching of Co-60 and (CS)-C-137 from spent ion exchange resins in cement-bentonite clay matrix
(Bulletin of Materials Science, 2003)
The leaching rate of Co-60 and Cs-137 from the spent cation exchange resins in cement-bentonite matrix has been studied. The solidification matrix was a standard Portland cement mixed with 290-350 (kg/m(3)) spent cation ...
Immobilization of Cs-137 in concrete
(Acta Chimica Slovenica, 2003)
To assess the safety for disposal of radioactive waste-cement-bentonite composition, the leaching of Cs-137 from a waste composite into a surrounding fluid has been studied. Leaching tests were carried out in accordance ...
Sorption of selenium anionic species on apatites and iron oxides from aqueous solutions
(Journal of Environmental Radioactivity, 2003)
The sorption of selenite and selenate ions from aqueous solutions was investigated on hydroxyapatite, fluorapatite, goethite and hematite, in order to simulate the behavior of radioactive selenium in natural or artificial ...
