“…Because it could induce psychopharmacological effects such as nervous excitation, stereotyped behavior, and insomnia, the assay methods for OA residues were widely studied. The reported methods are as following: HPLC-FL (Yorke and Froc 2000;Cohen et al 1999;Pouliquen and Armand 2000;Tyrpenou and Rigos 2004), HPLC-UV (Tourake et al 2001;Loussouarn et al 1997), capillary electraphoresis (Fierens et al 2000), and spectrophotometry (Dorota and Hanna 2003), etc. In all these methods, the spectrophotometric determination methods were extensively employed.…”

In Tris-HCl buffer (pH ¼ 7.43), Tb 3þ can react with oxolinic acid (OA) and form a 1:2 complex, which emits the intrinsic fluorescence of Tb 3þ . Based on this, a new fluorimetric method of determination of OA is developed. Under the optimum conditions, the enhanced fluorescence intensity of the system is proportional to the concentration of OA in the range of 1.5 Â 10 27 2.5 Â 10 25 mol/L, and the detection limit is 5.5 Â 10 29 mol/L. Recovery test was also satisfactory. The experiments indicated that the luminescence mechanism was attributed to the M Ã -M luminescence.
