| Abstract: | When oxytetracyline hydrochloride was heated in a boiling water bath, it reacted with sodium periodate and hydrogen peroxide in acidity medium, and then produced chemiluminescence signals. A new chemiluminescence method for determination of oxytetracycline hydrochloride using flow injection techniqe has been established.The linear range of the working curves was 1 .0 x 10-8 - 6 .0 x 10-6g/mL oxytetracycline hydrochloride.The detection limit of oxytetracycline hydrochloride was 4.3 x 10-9 g/mL. and relative standard deviation was 2.5% (Cs = 2.0 X 10-6 g/mL; n = 11). |
