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.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.
