中文摘要	研究了二(2,4,4-三甲基戊基)二硫代膦酸(HBTMPDTP)/正十二烷对不同水相介质中示踪量Am3+和Eu3+的萃取性能。结果表明,在水相介质为LiNO3,NaNO3,KNO3的体系中,3种阳离子Li+,Na+,K+对萃取没有显著影响;在水相介质为NaNO3,Na2SO4,NaClO4,NaCl,NaBr的体系中,不同阴离子对Am3+和Eu3+的萃取有一定影响。在水相介质为LiNO3,NaNO3,KNO3,NaCl,NaBr的体系中,分离因数均达到103以上,对Am3+和Eu3+有良好的分离效果;而在Na2SO4和NaClO4体系中,分离因数只有50和500左右,分离效果相对较差。; The extraction of tracer amount of Am~(3+) and Eu~(3+) from different aqueous media by bis(2,4,4-trimethyl) dithio phosphinic acid(HBTMPDTP)/n-dodecane was studied.The results show that in the solutions of LiNO_(3),NaNO_(3) or KNO_(3),the different cations show no remarkable effect on the extraction of Am~(3+) and Eu~(3+);in the aqueous solutions containing NaNO_(3),Na_(2)SO_(4),NaClO_(4),NaCl or NaBr,the different anions affect the extraction of Am~(3+) from Eu~(3+) and their separation to some extent.In the solutions of LiNO_(3),NaNO_(3),KNO_(3),NaCl or NaBr,HBTMPDTP has a good ability to separate Am~(3+) from Eu~(3+) with a separation factor that is more than 10~3.Lower separation factor of about 50 and 500 are obtained in Na_(2)SO_(4) and NaClO_(4) aqueous solutions,respectively.
