Abstract

In this paper, we found a new enhancement fluorescence system La-Tb-1-cyclopropyl-6-fluoro-1,4-dihydro-4-oxo-7-(1-piperazinyl)-3-quinolinecarboxylic acid (or ciprofloxacin, CPFX)-sodium dodecylbenzenesulfonate (SDBS), and the characteristic fluorescence of the La-Tb-CPFX-SDBS system was studied in detail. The effect of the experimental conditions on the fluorescence intensity was defined. By adding a suitable amount of La3+ to the Tb-CPFX-SDBS system, the fluorescence can be enhanced approximately three-fold. The fluorescence intensity is a linear function of europium up to a limit of 5.0 x 10(-10) mol/l. The system was used for determination of terbium in rare earth samples with satisfactory results. The mechanism of fluorescence enhancement is also discussed. (C) 2001 Elsevier Science B.V. All rights reserved.
