Abstract AITranslate

Rapid adsorption of radioactive substances is of great significance in emergency situations.A novel approach combining S-defect introduction and in situ phosphorization was employed to synthesize phosphorized WS2(WS2-PO4)for ultra-efficient uranium extraction.At an initial U(VI)concentration of 50 mg·L-1,the adsorption of U(VI)by WS2-PO4 nanosheets exceeds77%within just 1 min,with high selectivity(SU=78.7%)and good adsorption capacity of 268.82 mg·g-1.The phosphate groups have grown on the S defects and taken part in U(VI)extraction through surface complexation,leading to fast,reusable,and highly selective uranium adsorption,showing great potential in emergency treatment of radioactive nuclear wastewater.
