摘要
研究了在磷酸介质中 ,由于亚硝酸根催化作用 ,溴酸钾能够氧化藏红 T使之褪色 ,建立了测定痕量亚硝酸根的新方法 ,并探讨了这一催化反应的动力学条件 .其线性范围为 0～ 5.6 μg/ L,检出限为 2 .0× 1 0 - 8g/ L.用于纯净水中的亚硝酸根测定 。
A new spectrophotometric method for the determination of trace nitrite was studied .The method is based on the potassium bromate oxidizing safranine T because of nitrite catalytic agent in phosphoric acid medium.The linear range for the determination is 0～5.6 μg/L NO - 2.The limit of detection is 2.0×10 -8 g/L.The method has been applied to the determination of trace nitrite in purified water.
