摘　　要：近年来,国内外已报道的测定NO2-的方法很多,有紫外光度法、增敏光度法、极谱法、离子色谱法、催化光度法、催化电位法、流动注射分析光度法、漆酚树脂传感器直接电位法等;这些方法虽然各有一些优点,但也有其局限性和缺点。要想建立一个完善的测定亚硝酸盐的方法体系,还应从反应机理、反应条件、干扰离子的消除等多方面着手研究。There are many methods that have been reported for measuring NO2-at home and abroad in recent years. Such as ultraviolet luminosity, increasing sensitivity luminosity, polarography, ion chromatography, catalytic luminosity, catalytic potential, flow injection analysis luminosity, bakelite varnish resin sensor direct potential, etc. These methods have their each merits as well as their limitations and demerits. If we want to set up a perfect method system of measuring Nitrite, we should research from reaction mechanism, reaction conditions, elimination of interference ions, and so on.
