Sorption and desorption studies of some radionuclides by soil samples. Vol. 4

Abstract

The different factors influencing the sorption/desorption of {sup 137} Cs, {sup 60} Co, {sup 241} Am and {sup (152+154)}Eu by soil samples of Inshas area were investigated. Mineralogical analysis of the soil samples were carried out. The amount sorbed per gram soil (X/m) increased as the carrier concentration [C] increased from (10{sup -9} to 10{sup -}1 mol) following a freundlich type isotherm. The distribution coefficient [K d] of the radionuclides was found to be affected by pH. The presence of K{sup +}, Ca{sup 2+}, and Fe{sup 3+} as competing ions decreases the sorption capacity of the radioisotopes studied. The presence of complexing agents has a significant effect on the mobility of these radioisotopes. On the basis of the results obtained an attempt is being carried out to calculate different transport rates of the relevant isotopes in the investigated media. The mathematical model for the dispersion of the radioisotopes investigated in the groundwater environment was also elucidated. 4 figs., 2 tabs.
