Abstract:
The color fading reation on potassium bromate with Victoria green stand G by the catalysis of nitrite in hydrochloric acid medium was studied. The experimental condition offlow injection spectrophotometric method for the determination of trace NO2- was optimized. The linear range for the determination of nitrite is 0.00～0.30 mg/L and 0.30～ 2.00 mg/L, the solpes of standard curves are 0.708 and 0.339 respectively, the analytical speed is 80/h. It has been used todetermine trace nitrite in the collanae lake water, fishpond water, power plant waste water and well water. The results are satifactory.
