Synthesis of Quinoline/Phenanthroline Impregnated Sugarcane Bagasse for Recovering Uranium(VI) and Thorium(IV) from their Solutions.

This present research aims to synthesize and investigate the adsorption potential of sugarcane bagasse (SCB) impregnated with 8 hydroxy quinolone 8‐(HQ) and 1,10 phenethroline (phen) to prepare impregnated sugarcane bagasse (ISCB) for removal UVI and ThIV. The effects of the operating parameters, including pH of the solution, contact time, initial concentration, temperature, dose and interfering ions on the adsorption efficiency were investigated to identify an optimal condition. The characterization of SEM‐EDX and FTIR analyses shows that ISCB has a porous structure and carbon‐containing functional groups. The adsorption result revealed that ISCB removed 98 % for both UVI and ThIV. The result obtained fitted well for Langmuir isotherms model with 185.19 mg·g–1 and 250 mg·g–1 as theoretical capacity for UVI and ThIV respectively. The adsorption process followed the pseudo‐second‐order kinetic model. In conclusion, this study proved that ISCB has the potential to be used as an effective and low‐cost adsorbent to remove UVI and ThIV. Finally we obtain products from thorium as ThO2 and uranium as Na2U2O7 from Abu Rushied leach liquor. [ABSTRACT FROM AUTHOR]
