Abstract
Modified pomegranate peel was utilized as a sorbent for the biosorption of uranium(VI) from the aqueous solution. The biosorbent was characterized by infrared spectroscopy with Fourier transformation, energy dispersive X-ray fluorescence spectrometry, particle size analyser and determination of pHpzc. “Under optimized experimental conditions” the maximum adsorption capacity was 93.40 mg L−1. The equilibrium data fitted well to the Freundlich’s and Temkin’s isotherm model. Calculated data from applied kinetics model showed best agreement to the pseudo-second order model. Thermodynamic study showed the adsorption process is endothermic and nonspontaneous.
