Removal of Uranium (VI) from Aqueous Solution using Low Cost and Eco-Friendly Adsorbents

Abstract

Adsorption process is an important technique in separation processes, which is used in heavy metals removal from aqueous solution. Orange peel has been investigated for the adsorption of uranium ions from aqueous solution.The parameters of pH, contact time, initial uranium ion concentration, temperature and adsorbent dose have been investigated in batch experiments. The adsorption kinetics were described using pseudo-second order model and the adsorption isotherms were described by Langmuir and Freundlich isotherms which indicate that the uranium adsorption onto orange peel fitted well with Langmuir isotherm.
