Abstract
The effect of surfactant micelles and albumin on the fluorescence warfarin of and the fluorescence of Eu3+ and Tb3+ sensitized by warfarin and the second ligand is studied. It was shown that sensitized fluorescence in the system Eu3+-tenoyltrifluoroacetone-warfarin allows a 3800-fold reduction of the detection limit for warfarin. The developed procedure was used to determine warfarin in soil.
