A review on the use of high-performance liquid chromatography coupled with electrochemical detection (HPLC-ED) for the measurement of nitrite (NO2-) and nitrate (NO3-) is presented. HPLC-ED has been used for the determination of NO2- and NO3- in food, biological and environmental samples. Analysis of the current literature indicates that the measurement of NO2- and NO3- by the HPLC-ED procedure is more sensitive, selective and faster than methods based on UV absorption, photometry, fluorometry or chemiluminescence.
本文综述了高效液相色谱-电化学检测法（HPLC-ED）用于测定亚硝酸盐（NO2-）和硝酸盐（NO3-）的相关情况。HPLC-ED已用于食品、生物和环境样品中NO2-和NO3-的测定。对现有文献的分析表明，采用HPLC-ED法测定NO2-和NO3-比基于紫外吸收、光度法、荧光法或化学发光的方法更灵敏、更具选择性且速度更快。
