Abstract
We have found that a mixture of tri-n-octylamine (TOA) and di-n-hexylsulfide (DHS) in CHCl3 displays synergistic extraction of Ru(III) from aqueous HCl. Approximately 55% of Ru(III) was extracted by a 0.25 M TOA–0.25 M DHS system, whereas a single extractant, 0.25 M TOA or 0.25 M DHS, achieves hardly any Ru(III) extraction. Job plots of the extraction of Ru(III) from 5 M HCl aqueous solution indicate formation of a complex with 1:2:1 Ru(III):TOA:DHS stoichiometry. UV-Vis absorption spectra of the extracted Ru(III) complexes suggest that a DHS molecule is bound to the Ru(III) ion in the inner coordination sphere.
我们发现三正辛胺(TOA)和二正己基硫化物(DHS)在CHCl3中的混合物显示出从水溶液HCl中萃取Ru(III)的协同作用。大约55%的Ru(III)被0.25 M TOA - 0.25 M DHS系统提取，而单独的萃取剂，0.25 M TOA或0.25 M DHS几乎不能提取任何Ru(III)。从5 M HCl水溶液中提取Ru(III)的工作图表明，络合物的形成具有1:2:1的Ru(III):TOA:DHS化学计量。提取的Ru(III)配合物紫外可见吸收光谱表明，DHS分子在内配位球中与Ru(III)离子结合。
期刊介绍：
Solvent Extraction Research and Development, Japan (Solvent Extr. Res. Dev., Jpn.) is a periodical issued from Japan Association of Solvent Extraction (JASE) containing papers dealing with all aspects of solvent extraction and their related methods, underlying principles, and materials. Original articles, notes, technical reports, and critical reviews will be considered for publication. Original articles must be of reasonably broad scope and significance to the solvent extraction. Notes will originally describe novel work of a limited nature or especially significant work in progress. Authors can contribute some information of novel techniques, equipment or apparatus, reagents and diluents for solvent extraction as technical reports. Critical reviews will be received from the authors to whom the editorial committee asked to contribute.
