STUDY ON THE FLUORESCENCE OF THE SYSTEM SAMARIUM/2-BENZOYL-1,3-INDONE/CETYLTRIMETHYLAMMONIUM BROMIDE AND ITS ANALYTICAL APPLICATION
摘要:
The fluorescence system Sm-BID-CTAB has been discovered and its fluorescence characteristics have been studied.The excitation and emission wavelengths are 360 nm and 650 nm,respectively.The fluorescence intensity is a linear function of the concentration of samarium in the range 5.0×10-5-2.0×10-7mol/L.The detection limit is 5.0×10-9 mol/L.Standard addition method is used for the determination of samarium in synthetic rare earth sample with satisfactory results.
