摘要
依据硝酸盐与二苯胺在浓硫酸介质中反应生成有色物质的原理,在目视比色法的基础上建立了简便、快捷、可靠地测定粒碱中硝酸盐含量的方法,用于实际样品的测定,实用效果较好。
According to the principle of forming colored substances in the reaction of nitrate and biphenyl amine in concentrated sulfuric acid, and on the basis of visual colorimetry, a quick, simple and reliable method of determining nitrate content in granular caustic soda was established. Better effects were obtained in determination of practical samples .
