Abstract: The fluorescence properties of Eu(Ⅲ)-PhenNO-TTA-emulsifier OP system have been studied (phen NO:phenanthroline-N-oxide,TTA : thenoyltrifluoroacetone).The system has been used for determination of trace amount of Eu(Ⅲ) in some samples with satisfactory results. The determination limit was observed of7.0×10-14mol/L.

Key words: Eu(Ⅲ), phenanthroline-N-oxide, fluorescence analysis
