HDEHP萃取单核Rh(Ⅲ)和Ir(Ⅲ)水合阳离子的机理

MECHANISM OF THE EXTRACTION OF MONONUCLEAR Rh(Ⅲ) AND Ir(Ⅲ) AQUA CATIONS BY HDEHP

摘要: <正> 用UV-Vis,IR及斜率法研究HDEHP的苯溶液萃取单核Rh(Ⅲ)和Ir(Ⅲ)水合阳离子的机理,证明Rh(Ⅲ)和Ir(Ⅲ)以离子对M(H_2O)_6(HA_2)_3(HDEHP简写为HA)的形式进入有机相。

Abstract: The mechanism of the extraction of mononuclear Rh(Ⅲ) and Ir(Ⅲ) aqua cations by HDEHP in benzene is studied with UV-Vis, IR and slope analysis. The experimental results show that both Rh(Ⅲ) and Ir(Ⅲ) are extracted as ion-pairs M(H2O)6 (HA2)3 (M=Rh, Ir; HA-HDEHP) into the organic phase.
