| Abstract: | In this study, the co-luminescence effect of Y~(3+)-Eu~(3+)-metacycline (MTC)-cetyltrimethylammonium bromide (CTMAB) system was studied and the luminescence mechanism of the system was discussed. Based on the co-luminescence effect, a fluorescent method for the determination of MTC has been proposed. Ihe effects of various factors on the system were investigated in detail. Under optimum conditions, a linear relationship was obtained between the fluorescence intensity and the MTC concentration in the range of 1.0×10~(-7) mol/L～1.5×10~(-5) mol/L. The detection limit of MTC was 3.6×10~(-8) mol/L. This system was used for the determination of MTC in the tablet samples with satisfactory results. |
