We present a study of uranium (VI) adsorption in aqueous solutions by magnetic oxine (ferroferric oxide/oxine composite). Batch experiments of uranium (VI) adsorption were conducted, investigating the significance of solution pH, contact time, ionic strength, and temperature on uranium sorption efficiency. The results suggest that maximum adsorption capacity is 125mgg−1 when the initial uranium (VI)...
The adsorption of Rhodamine-B (RhB) onto treated rice husk-based activated carbon was investigated in this paper. The influences of initial RhB concentration, temperature and pH on dye adsorption were analyzed. Initial RhB concentration and temperature played important roles in this adsorption process, and pH had a little effect on RhB adsorption. Adsorption kinetics, equilibrium and thermodynamics...
Magnetic Mg–Al layered double hydroxide was modified with citrate acid using a ion-exchange technique. It showed higher adsorption capacity for the uranium(VI) ions compared with magnetic Mg–Al layered double hydroxide without intercalating with citrate. This increasing capacity was mainly attributable to the formation of the citrate–metal complexes in the interlayer of the magnetic citrate·Mg–Al...
