三正辛基氧化膦萃取钯的研究
摘要:
本文研究了用三正辛基氧化膦(TOPO)煤油溶液从盐酸介质中萃取钯及用硫脲反萃钯的条件。用等摩尔系列法、饱和法、化学分析法和斜率法确定了萃合物的组成。用紫外-可见光谱法探讨了TOPO萃取钯的机理。

EXTRACTION OF PALLADIUM WITH TOPO
Abstract:
In this paper, the extraction of palladium with tri-n-octyl phosphine oxide (TOPO) from hydrochloric acid solution and its back-extraction with thiourea have been studied, The composition of the extraction complexes determined experimentally by the methods of equi-molal series, saturation,solpe and chemical analysis. The extraction mechanism of palladium with TOPO were discussed through UV-VIS spectrometric determination. The extractionprocess can be expressed as:2PdCl4(a)2-+2TOPO(o)⇌Pd2Cl4·2TOPO(o)+4Cl(a)-
