Preparation of Poly-Aniline-Magnetic Porous Carbon Composite for Using as Uranium Adsorbent

Rice husk as one of the agricultural by-products has been used as a starting material for the production of porous carbon (PC), the obtained porous carbon has been modified by poly aniline and magnetized to form poly aniline magnetic porous carbon composite (PA-MPC). The prepared PA-MPC has been characterized and examined for uranium adsorption from its pregnant solutions. The effect of the controlling parameters (pH; Contact time, temperature, initial uranium concentration, and adsorbent dosage) have been optimized. The obtained results indicate that the adsorption is pH dependant. The equilibrium data were well described by langmuir isotherm with theoretical capacity 94.3 mg/l at room temperature. These results demonstrate the potential use of this adsorbent for uranium ions removal from its pregnant solutions.
