| 摘 要： | The solvent extraction of U(Ⅵ) from nitric acid solution was studied with one new extractant, 4-p-methylbenzoyl-2,4-dihydron-5-methyl-2-phenyl-pyrazol-3-thione (HMeBMPPT), synthesized via acylation, chlorination and sulfurication of the starting material 1-phenyl-3-methyl-pyrazolone-5(PMP) in high yield. The structure of the new extractant was confirmed by means of elemental analysis, MS, 1H NMR and X-ray diffraction. The effects of diluent, temperature, the concentrations of nitric acid, and the concentration of extractant on the extraction were investigated and the extraction mechanism is suggested.
