亚硝酸盐危害与一种新的亚硝酸盐含量测定方法的探讨

亚硝酸盐俗称“硝盐”，主要指亚硝酸钠和亚硝酸钾，是一种白色不透明结晶的化工产品，形状极似食盐。亚硝酸盐是剧毒物质，同时还是一种致癌物质。酸性条件下利用亚硝酸盐具有氧化性的特性氧化KI生成I2，I2和淀粉作用灵敏地生成I2-淀粉蓝色络合物及产生特效反应，由此建立光度法测定食品中亚硝酸盐含量的新分析方法。

Discussion on the Hazard of Nitrite and a New Assay Method

Known as saltpeter, nitrite, a white opaque crystalloid like salt, is consisted of Sodium nitrite and potassium nitrite. It is a highly toxic substance and carcinogen. The new nitrite assaying method is based on photometry, since in the acid condition, according to its oxidability KI can be oxidized into I2, and I2-amylum blue clathrate and special reaction are produced by the reaction between I2 and amylum.
