摘　　要：研究了TBP、 5 0 %TAPO -煤油溶液在HCl介质中对铱 (Ⅲ )氯水配合物的萃物行为。结果表明 :当 [HCl]<3mol/L时 ,铱 (Ⅲ )氯水配合物在一定程度上被 5 0 %TAPO -煤油溶液萃取 ,且随着HCl浓度的增加 ,其萃取率降低 ;当 [HCl]>3mol/L时 ,其萃取率均很低 ,几乎不被萃取。通过对萃取后的水相、有机相紫外 -可见光谱和红外光谱的表征 。The extraction for aqua-chloroiridate(BFQⅢ)complexes in the HCl solution was studied with TBP and 50% TAPO-kerosene solution as extractants.The results show that effective extraction is difficult when HCl>3 0mol/L but 50% TAPO can extract them to a certain degree only in the low HCl concentration(<3mol/L).The experimental phenomena and results are discussed after the UV-and IR-spectra for their extracted aqueous and organic phases obtained.It is evident that the extraction aqua-chloroiridate(Ⅲ)complexes is belong in coordination and replacement extraction.
