【摘要】：氨氮(NH3-N)是溶解無機(jī)氮的重要組成之一,其含量是重要的營養(yǎng)鹽指標(biāo)。海水氨氮是上層海洋氮循環(huán)的重要組成部分,也是海洋浮游植物所必需的營養(yǎng)物質(zhì)之一。氨氮濃度與海洋生物生命活動(dòng)密切相關(guān),可直接影響海洋生物的正常生命活動(dòng),因此快速準(zhǔn)確地檢測(cè)海水氨氮濃度及其變化對(duì)研究海洋氮循環(huán)及開展海洋生態(tài)環(huán)境監(jiān)測(cè)至關(guān)重要。介紹了近年來海水氨氮的檢測(cè)方法,如靛酚藍(lán)分光光度法、熒光光譜法、化學(xué)發(fā)光法、色譜法、表面等離子共振法及電化學(xué)分析法,分析了不同方法的靈敏度、準(zhǔn)確性等特性,并對(duì)各類方法進(jìn)行了比較與展望。
[Abstract]:Ammonia nitrogen (NH3-N) is one of the important components of dissolved inorganic nitrogen, and its content is an important indicator of nutrients. Ammonia nitrogen in seawater is an important part of the upper ocean nitrogen cycle and one of the essential nutrients for marine phytoplankton. The concentration of ammonia nitrogen is closely related to the life activities of marine life and can directly affect the normal life activities of marine life. Therefore, rapid and accurate detection of ammonia nitrogen concentration and its changes in seawater is very important for the study of ocean nitrogen cycle and the monitoring of marine ecological environment. The methods for the determination of ammonia nitrogen in seawater in recent years, such as indigo blue spectrophotometry, fluorescence spectrometry, chemiluminescence, chromatography, surface plasmon resonance and electrochemical analysis, are introduced. The sensitivity and accuracy of different methods are analyzed. The comparison and prospect of all kinds of methods are also given.
