摘要:硝酸盐、亚硝酸盐主要用作防腐剂与着色剂应用于食品加工生产过程中,但有研究显示过量摄
入可能引起中毒或死亡,对其检测方法的研究也处于不断摸索优化阶段。本文主要对硝酸盐与亚硝酸盐的检
测方法研究进展进行了综述,并对相关检测方法进行对比介绍。目前。应用较多的检测方法有快速检测法
分光光度法、化学发光法、电化学方法、高效液相色谱法等。其中,快速检测法耗时较短,但不能实现对硝
酸盐和亚硝酸盐的准确定量:而光谱法在一定程度上解决定量问题,但该方法检测限普遍较高电化学方法
操作简便,但存在一定的不确定性;众多研究数据显示,色谱法具有操作简单、快速、灵敏度高等特点,在
众多领域应用最为广泛,尤其高效液相色谱法最为突出。气相色谱法在其基础上可实现硝酸盐与亚硝酸盐的
同时检測。本文也对高效液相色谱法进行重点介绍
