Uranium(VI) recovery from its leach liquor using zirconium molybdophosphate composite: kinetic, equilibrium and thermodynamic studies

A zirconium molybdophosphate composite was designed for the selective recovery of uranium ions. The synthesized composite was well-characterized using SEM, EDX, FT-IR and XRD. U(VI) ions recovery from their aqueous solution by the studied composite was investigated in terms of adsorption isotherm, a...

Description
Summary:A zirconium molybdophosphate composite was designed for the selective recovery of uranium ions. The synthesized composite was well-characterized using SEM, EDX, FT-IR and XRD. U(VI) ions recovery from their aqueous solution by the studied composite was investigated in terms of adsorption isotherm, and thermodynamics. The composite is highly efficient and selective in U(VI) ions capturing with Langmuir adsorption capacity of 192.3 mg/g. Results showed that the composite is highly efficient in removal for U(VI) ions from Abu Rusheid leach liquor. As well as, it exhibits long-term stability, reusability, and fast kinetic in capturing of uranyl ions from leach liquor.
