and the mechanism involved. In order to explore the involved process, speciation study was
carried out and it confirmed that U was present in the moderately reduced soil as a mixture
of U (IV) and U (VI) with U (IV) as dominating (71%) state. Sequential extraction of soil
samples showed that major fraction is bound to clay mineral (49.31%) followed by oxides
and hydroxide of Fe/Mn (19.58%), organic phase (10.75%), exchangeable (10.41%) and …
