目前 ,食品中硝酸盐氮含量测定 ,在食品理化检验国家标准方法中 ,采用镉柱还原法 (ＧＢ/Ｔ 5 0 0 9 1996) ,经我们多年使用 ,该法操作繁琐、费时 ,不适应大批样品检测 ,且使用大量镉粉容易造成环境污染。对此 ,建立一种实用、准确、简便、快速的测定方法十分必要。我们参考有关 At present, the determination of nitrate content in food, physical and chemical testing in the national standard method of food, the use of cadmium column reduction method (GB / T 5 0 0 9 1996), after many years of our use, the method of operation cumbersome, time-consuming, Sample testing, and the use of large amounts of cadmium easily lead to environmental pollution. In this regard, the establishment of a practical, accurate, simple and rapid determination of methods is necessary. We refer to it
