EXTRACTION OF U(Ⅵ) FROM NITRIC ACID SOLUTIONS WITH N-DECANYL ACYLMOPHOLINE (DMPHL) IN DIFFERENT DILUENTS

  • 摘要: 研究了在不同稀释剂中N 癸酰基吗啡啉(DMPHL)从硝酸介质中对铀(Ⅵ)的萃取。讨论了在不同稀释剂中硝酸浓度、萃取剂浓度及温度对D(U(Ⅵ))的影响。实验结果表明,在不同稀释剂中,N 癸酰基吗啡啉对U(Ⅵ)的萃取能力为:苯>环己烷>煤油>四氯化碳>氯仿。
    Abstract: The extraction of U((Ⅵ)) from nitric acid solutions with decanyl acylmopholine (DMPHL) in different diluents has been studied. The effect of aqueous nitric acid concentration,extractant concentration and temperature on distribution ratio has been investigated. The experimental results show that the extraction effciency of DMPHL for U(Ⅵ) increases in the order of chloroform,carbon tetrachloride,kerosene,cyclohexane and benzene. The mechanism of extraction reaction might be the same in different diluents.The maximun nitric acid concentration for highest D(U(Ⅵ)) is 5~6 mol/L and the composition of extracted complex is UO2(NO3)2·2(DMPHL)
