Synthesis, Characterization and Investigation of Cross-Linked Chitosan/(MnFe2O4) Nanocomposite Adsorption Potential to Extract U(VI) and Th(IV)

A cross-linked chitosan/(MnFe2O4) CCsMFO nanocomposite was prepared using co-precipitation methods and used as a nanomaterial to extract U(VI) Th(IV) from an aqueous solution based on adsorption phenomena. The contact time of experiments shows rapid extraction process within 30 min by the nanocomposite. pH acts critical role in determining qm value, where 3.0 best value both ions. pseudo-second-order equilibrium model illustrated kinetics modal process. Adsorption isotherm at is endothermic In contrast, exothermic reusability tested basic eluents suitable conditions for chemical stability nanocomposite; results show promising removal adsorbed onto with 77.27%, after 12 h Na2CO3 eluent. At same time, good 21.82%, 8 EDTA
