A new simple chemiluminescent method for the determination of chlortetracycline (Chlor-TC), oxytetracycline (Oxy-TC) and doxycycline (Doxy-TC) is described. This method is based on the europium(III) emission as a result of the energy transfer process from the excited product of the tetracyclines oxidation to the uncomplexed Eu(III). Under the optimum conditions, calibration graphs were obtained for 4x10(-7) to 2x10(-5) mol L(-1) of Chlor-TC; 2x10(-7) to 2x10(-5) mol L(-1) of Oxy-TC and 1x10(-7) to 3x10(-5) mol L(-1) of Doxy-TC. The method was successfully applied to the determination of these drugs in pharmaceutical and veterinary formulation and honey.
