Abstract: Scandium, yttrium and lanthanum have been extracted and separated by 1, 10-bis (1'-phenyl-3'-methyl-5'-oxopyrazol-4'-yl) -1, 10-decanedione in nitric acid.The extracted com-plexes were isolated and examined by elemental analysis, thermal analysis, UV, IR, 1H NMR,molar conductances and the solubility determinations.

Key words: bis acyl pyrazolone, extraction separation, scandium, yttrium, lanthanum
