Sorption and desorption of UO22+, Th4+ and Ru3+ on the synthetic analogue of muscovite

Sorption and desorption of UO22+, Th4+ and Ru3+ on the synthetic analogue of the mica mineral muscovite has been studied by a batch technique. The synthesized gel was characterized by XRD, EDXRFS, FTIR, TGA and SEM and was found to have a composition K1.4Al4.2(Si6Al2O20)(OH)4 . 2H2O. Different parameters like acid concentration, contact time, amount of gel, composition of gel: OPC admixture, effect of temperature, desorption of metal ions from loaded muscovite and effect on crystal morphology due to loading of metal ions were studied. The results has been expressed in terms of distribution coefficient (Kd).
