Zm. Topilova et al., LUMINESCENT DETERMINATION OF LANTHANIDE TRACES IN URANIUM, THORIUM, AND SCANDIUM COMPOUNDS, Radiochemistry, 38(6), 1996, pp. 516-519
Novel long-chain fluorinated derivatives of acetylacetone with C6F13 a
nd C8F17 radicals are promising for luminescent determination of samar
ium (10(-3)-10(-2) %), europium (10(-4)-10(-3) %), and neodymium and y
tterbium (10(-1)%) traces in uranium, thorium, and scandium compounds.
