Abstract
A new fluorimetric method for the determination of epinephrine is established by rare earth co-luminescence effect of Tb-Gd-E-Tris system. Under optimum conditions, a linear relationship has been obtained between the fluorescence intensity and the concentration of epinephrine in the range of 1.8Â ÃÂ 10â8 to 2.5Â ÃÂ 10â6Â mol/l, and the detection limit is 4.5Â ÃÂ 10â9Â mol/l (S/NÂ =Â 3). The method is applied for the determination of epinephrine in injection and the recovery test in urine by standard addition method, and the results obtained are satisfactory. The mechanism of the co-luminescence in the system was also discussed.
