Abstract
Biomass waste is recognized as potential raw material for many adsorbents. In this study orange peel biochar (OP) was modified with amidoxime group. The consequent amidoximated orange peel biochar (OP-AO) was investigated to reveal potential for the removal of U(VI) from aqueous solution. Essential parameters for the adsorption such as pH, initial U(VI) concentration, adsorption time and temperature were determined. The SEM, FT-IR, XPS, BET analyses and Zeta potential test were used to characterize the structure of amidoximated biochar and the adsorption mechanisms. Kinetics, isotherms and thermodynamics were studied. The results showed that modification with amidoxime group improved the U(VI) adsorption capacity of the original biochar (Qmax (OP-AO) = 382.89 mg/g > Qmax (OP) = 155.44 mg/g). The obtained results showed that the used biochar is a promising adsorbent for the specific uranium separation.
