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.
