ABSTRACT
In this work, uranium(VI) sorption from aqueous sulphate medium using tri-n-octylamine impregnated Siplite LX-16 resin has been investigated using batch experiments. The sorption parameters including aqueous pH, initial U(VI) concentration, aqueous solution volume to impregnated resin weight (v/w) ratio, contact time and the sorption temperature have been studied. The experimental data have been examined by both equilibrium isotherms and kinetic sorption models. It was found that, the sorption process of U(VI) onto the working resin follows both Langmuir and Freundlich isotherms and quite agrees with the pseudo-second order and intraparticle diffusion models.
Highlights
TOA/Siplite LX-16 was used for uranium sorption from suphfate medium.
Maximum sorption capacity of U(VI) was found to be 92.74 mg/g at optimized conditions.
Equilibrium, kinetics and thermodynamic studies were performed.
