摘  要:氨氮(NH3-N)是溶解无机氮的重要组成之一,其含量是重要的营养盐指标。海水氨氮是上层海洋氮循环的重要组成部分,也是海洋浮游植物所必需的营养物质之一。氨氮浓度与海洋生物生命活动密切相关,可直接影响海洋生物的正常生命活动,因此快速准确地检测海水氨氮浓度及其变化对研究海洋氮循环及开展海洋生态环境监测至关重要。介绍了近年来海水氨氮的检测方法,如靛酚蓝分光光度法、荧光光谱法、化学发光法、色谱法、表面等离子共振法及电化学分析法,分析了不同方法的灵敏度、准确性等特性,并对各类方法进行了比较与展望。Ammonia nitrogen(NH3-N) is an important component of dissolved inorganic nitrogen, and its content is an important index of nutrition salt. Ammonia nitrogen in seawater is an important part of the upper ocean nitrogen cycle,and also an essential nutrient for marine phytoplankton. Ammonia nitrogen concentration is closely related to life activities of marine organisms, and ammonia nitrogen can affect the normal life activities of marine organisms. Therefore, it is crucial to rapidly and accurately detect ammonia nitrogen concentration and its change in seawater for studying ocean nitrogen cycle and developing oceanic ecology environmental monitoring. Determination methods of ammonia nitrogen in seawater developed in recent years,including indophenol blue spectrophotornetry, fluorescence spectrometry, chemiluminescence, chromatography, surface plasmon reso- nance and electrochemical analysis, are reviewed. The characteristics of sensitivity and accuracy for different methods are analyzed, and they are also compared and prospected.
