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 U VI and Th IV . 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 U VI and Th IV . The result obtained fitted well for Langmuir isotherms model with 185.19 mg · g –1 and 250 mg · g –1 as theoretical capacity for U VI and Th IV 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 U VI and Th IV . Finally we obtain products from thorium as ThO 2 and uranium as Na 2 U 2 O 7 from Abu Rushied leach liquor.
