The extraction of uranium ((Ⅵ) from nitric acid solution with N-octanoyl-2-methylpiperidine (OMPPD)in eight diluents and the dependence of distribution ratio on temperature and concentrations of both aqueous nitricacid and OMPPD were investigated. The interaction among OMPPD, the extracted species and diluent has been dis-cussed. The experiments show that the extraction ability of OMPPD decreases gradually for eight diluents in the fol-lowing order: benzene, toluene, n-octane, sulfonated kerosene, cyclohexane, carbon tetrachloride, 1,2-dichloroetheneand chloroform. It cannot be interpreted only on the basis of polarity of diluents.
