| Abstract: | The fluorescence property of complexes of samarium and europium with tetracycline antibiotics, such as tetracycline (TC), oxytetracycline (OTC), doxycycline (DOTC) and chlortetracycline(CTC) was reported. When determining europium and samarium with TC, OTC, DOTC, the detection limit could reach 0. 09, 0. 14, 0. 19 ng/mL for europium and 38. 2, 20. 5, 26. 0 ng/mL for samarium, respectively. It is not appropriate to determine europium and samarium with CTC because the characteristic fluorescence of europium and samarium was very weak. Tetracycline was chosen as optimum reagent, considering the sensitivity and stability of the system. |
