Abstract: The separation of Sc(III), Y(III), La(III), Fe(III, II), and Sn(IV, II) in hydrochloric acid solution by the extraction method with 1,10-bis(1-phenyl-3-methyl-5-oxopyrazol-4-yl)decane-1,10-dione has been investigated. The solid extracts of Sc(III) and Fe(III) have been prepared by this method, and their solubility, molar conductivity, thermal stability, UV, IR, and ¹H  NMR spectra have been determined. Their extraction mechanism and the structure of the extractive are discussed, too.
