Interphase distribution of chloride complexes of rhody (III), ruthenia (III) in extraction systems based on liquid anion exchangers

Abstract

The interphase distribution of associates of chloride complexes of Rhodium (III), Ruthenium (III) with liquid anion exchangers in chloroform has been studied by spectrophotometry, inductively coupled plasma optical emission spectrometry. The regularities of construction and properties of primary alkylamynes with normal construction (C₁₂-C₁₈), multiradical tertiary amines influence on their ability to extract highly-charged complexes of Rhodium (III), Ruthenium (III) from concentrated chloride solutions. Decrease in the volume of tertiary alkylamine radicals by substitution of two alkylamines for methyl compounds allows to reduce steric effects and use heterogeneous tertiary alkylamines such as dimethyl n-dodecylammonium to extract highly charged complexes of Rhodium (III), Ruthenium (III). The outer-sphere mechanism of extraction of high-charge complexes of Rhodium (III), Ruthenium (III) and composition of the extracted associate Rhodium (III) is determined by molecular spectrophotometry, IR spectroscopy, chemical analysis of saturated organic phase, molar ratios
