摘　　要：本文研究了Ｐ２０４和石油亚砜协同萃取钒（Ｖ）的萃合物组成，计算了协萃反应的协萃平衡常数，通过电子吸收光谱和红外光谱探讨了协萃物的结构。结果表明：在Ｐ２０４和ＰＳＯ协萃体系中，Ｐ＝Ｏ、Ｐ－Ｏ－Ｈ基团与ＶＯ＋２键合。The composition of the synergitic complex from the synergitic extraction of VO + 2 by P 204 and PSO is strudied. The equilibrium constant of the synergism reaction is calaculated. The structure of the synergitic complex is studied by electronic and infrared spectrum. The results show that, in the synergitic extraction system by P 204 and PSO, the P=O and P-O-H groups all bond with VO + 2.
