Sorption of Co, Cs, Sr and I onto argillaceous rock as studied by radiotracers</p> </p>

Radiochemistry

“…Adsorption behaviour on cement 269 (U) and ceramics 270 (Eu) has also been reported. In a more general way the adsorption of tin and plutonium 271 and also caesium, cobalt, strontium and iodine 272 onto clay, has been studied, as well as, in the latter case, the subsequent diffusion 273,274 of these elements through clay like material. Even more general have been studies of the way in which radioisotopes, usually of heavy metals, behave in tank waste sludges, 275 in peat, 276 in different soils 277 and in alluvial sediments.…”

Sorption and retardation of strontium in saturated Chinese loess: experimental results and model analysis

“…Conventionally, geological burial and landfill are often employed for disposal of nuclear wastes. Waste radionuclides, however, can be leached from the disposal sites, and may contaminate soil and groundwater and reach the biosphere (Mell et al, 2006). As a result, it is important to understand the fate and transport of waste radionuclides in the subsurface for proper disposal of nuclear wastes.…”

“…A number of physicalechemical processes have been found responsible for sorption of Sr on soil: reversible ion-exchange, precipitation of various forms of hydroxides, oxides, carbonates and sulfates, oxidationereduction reactions, complexation, and formation of colloids during waste package reactions (Mell et al, 2006). The extent of Sr sorption in a given environment is influenced by pH and Eh of the soil and groundwater (Khan, 2003;Kohli cková and Jedináková-K ri zová, 1998;Tsukamoto et al, 2006;Wang and An, 2004).…”

Sorption and Retardation of ⁹⁰Sr²⁺in Loess Media

“…To facilitate assessment of the potential environmental impact of 90Sr, it is important to beat out the transport mechanisms that occur in soil and groundwater. In fact, a number of physical-chemical processes are connected with sorption of Sr on soil [5,6]. The sorption behaviour of Sr is associated with pH and Eh of the soil environment.…”
