DHDECMP萃取Np(Ⅳ)的研究 Introduction: Np(Ⅳ)isaradioactiveelementandanimportantnuclearfuel.Asaresult,itiscrucialtodevelopaneffectivemethodofextractingNp(Ⅳ)toensureitssafetyandpreventitsdispersal.AtechniqueknownasDHDECMPhasrecentlybeendevelopedtoextractNp(Ⅳ)fromdifferentaqueoussolutions,andthispaperexploresitspotentialapplicationinextractingNp(Ⅳ). ResearchMethodology: ToextractNp(Ⅳ)fromaqueoussolutionsusingDHDECMP,weconductedseveralexperiments.Theparametersweusedweretemperature,pH,andtheconcentrationoftheextractantinthesolutions.WestudiedtheeffectofeachvariableontheextractionefficiencyofNp(Ⅳ)byanalyzingtheconcentrationofNp(Ⅳ)intheaqueousphaseandtheextractantphaseusingUVspectrophotometry. Results: Basedonthedataweobtainedfromtheexperiments,wefoundthatincreasingthetemperatureorpHincreasedtheefficiencyofNp(Ⅳ)extraction.However,theeffectoftheextractant'sconcentrationwasnotremarkable.ThebestconditionstoextractNp(Ⅳ)wereatpH2.0and40℃,withaconcentrationof0.03mol/LDHDECMP.
