Me, Ph). Their extraction capability toward UVI and a number of tervalent lanthanides (LaIII, NdIII, HoIII, YbIII) was studied. Efficiency and selectivity of these ligands in the extraction of f-elements from nitric acid solutions to chloroform were compared with extraction properties of a model phosphine oxide-type phosphorylurea MePhP(O)NHC(O)NHC8H17-n and carbamoylphosphine oxide Ph2P(O)CH2C(O)NBu2

辛胺处理导致
磷酸脲 R1R2P(O)NHC(O)NHC8H17-n (R1 = EtO, PhO; R2 = Me, Ph)。研究了它们对 UVI 和许多三价
镧系元素(LaIII、NdIII、HoIII、YbIII)的提取能力。将这些
