Macroscopic batch sorption study has been carried out to measure distribution coefficient (Kd) of uranium, thorium and their daughter products, radium and polonium, on soil samples collected from a proposed uranium mining site in India. Results showed high Kd values for Th(IV) and Po(IV) (log Kd ~4), while lower Kd values were obtained for U(VI) with the...
Soils and ground waters have been extensively exposed to pollution by heavy metals from various anthropogenic sources. The presence of these metals in soils poses a significant environmental hazard, and one of most difficult contamination problems to solve. Description of some sorption and migration phenomena involving Pb, Zn, Ni and Cu in the surface layer of soil and sewage sludge compost was the...
