A sensitive and selective method for the determination of norepinephrine is described. Norepinephrine was oxidized by mercury(II)nitrate and the oxidation product was condensed with ethylene diamine (EDA) to form strong fluorescent compound. The addition of acetone enhances the light intensity. The measurement was carried out at 507 nm with excitation at 420 nm. Effects of pH, oxidizing agent, ethylene diamine, acetone and heating time on the condensation reaction were examined. A linear relationship was obtained between the fluorescence intensity and the concentration of norepinephrine in the range of 1.0 × 10-6 M to 1.0 × 10-4 M; the correlation coefficient and the detection limit are 0.99751 and 3.0 × 10-7 M respectively. This method was used for the determination of norepinephrine in injection and urine samples.
