【摘要】 研究了ＤＨＤＥＣＭＰ－十氢萘－二甲苯在硝酸体系中对镅（Ⅲ）的萃取和酸性萃取剂ＨＰＭＢＰ及ＨＴＴＡ与ＤＨＤＥＣＭＰ对镅的协同萃取。结果表明，在ｐＨ＝１─３之间，浓度为０．３ｍｏｌ／１时，主要协同萃合物是Ａｍ（Ａ）＿２·ＮＯ＿３·ＨＡ·２ＤＨＤＥＣＭＰ（ＨＡ代表ＨＰＭＢＰ或ＨＴＴＡ）。ＤＨＤＥＣＭＰ与ＨＰＭＢＰ、ＨＴＴＡ协同萃取Ａｍ￣（３＋）的协萃系数分别为１０￣２─１０￣３和１０￣２─１０￣４。更多还原

【Abstract】 The extraction properties of Americium（Ⅲ）in the system of HNO₃using DHDECMP/de calin-xylene is studied.Acidic ligands HPMBP and HTTA are selected to study the synergistic extraction of Am￣（3+）,The results show that the main extract form is Am（A）₂·NO₃·HA·2DHDECMP（HAstands for HPMBP or HTTA）.The synergistic coeffients of DHDECMP with HPMBP and HTTA are 10￣2～10￣3 and 10￣2～10￣4 , respectively.更多还原
