Abstract

The extraction behavior of rare-earth elements on silica gel impregnated with petroleum sulfoxide (PSO) from an aqueous NH₄SCN solution was systematically investigated. With a batch method, the distribution ratios and separation factors of rare-earth elements in this medium were determined. The composition of the extracted complex was determined by a slope analysis as being (PSO)₃RE(SCN)Cl₂. Through the IR spectra it was proved that the oxygen atom of the >S=O group in PSO coordinates the rare-earth element to form the extracted complex. The standard enthalpy (ΔH°_RE) in the process of PSO-extraction of rare-earth elements was measured; ΔH°_RE indicated that the distribution process of the rare-earth element between the PSO-silica gel stationary and NH₄SCN mobile phases is an exothermic process. Moreover, the stabilities of the extracted complexes are discussed in terms of Δ(ΔG°)_Ln/Y, the relative standard free energy of complex formation (ΔG°_Ln-ΔG°_Y). The quantitative separation of yttrium from lanthanides has been achieved by this method, which was also used in an analysis for yttrium in the Jiangxi ionic-type rare-earth ores of China.
