-
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.
