Abstract

Nitrate is an important pollutant found in environmental samples. Nitrate and nitrite pose various environmental as well as health hazards. Different methods of determining nitrate in various environmental samples developed during previous years include spectrophotometric, chemiluminescence, electrochemical detection, chromatographic, capillary electrophoretic, spectrofluorimetric methods. Out of these, methods based on spectroscopic detection of nitrate have been discussed in this review article due to their easy availability, high sensitivity, low detection limit, economical and facile nature. Methods based on spectrophotometry, Raman Spectroscopy, IR and FTIR Spectroscopy, atomic absorption spectroscopy (AAS), fluorescence spectroscopy, chemiluminescence, mass spectroscopy, molecular emission cavity analysis (MECA), electron paramagnetic resonance spectrometry (EPR) and nuclear magnetic resonance spectroscopy (NMR) have been reviewed. The basic principle, detection limits, detection range, RSD%, sample throughput/h, advantages and disadvantages have been discussed.

环境样品中亚硝酸盐和硝酸盐的光谱测定方法综述

硝酸盐是环境样品中的一种重要污染物。硝酸盐和亚硝酸盐会对环境和健康造成各种危害。近年来发展起来的各种环境样品中硝酸盐的测定方法包括分光光度法、化学发光法、电化学检测法、色谱法、毛细管电泳法、荧光光谱法等。其中，基于光谱的硝酸盐检测方法因其简便易行、灵敏度高、检出限低、经济方便等特点，本文进行了综述。综述了基于分光光度法、拉曼光谱法、红外和红外光谱法、原子吸收光谱法(AAS)、荧光光谱法、化学发光法、质谱法、分子发射腔分析(MECA)、电子顺磁共振光谱法(EPR)和核磁共振波谱法(NMR)的方法。讨论了该方法的基本原理、检出限、检出范围、RSD%、样品通量/h、优缺点。

期刊介绍： Talanta provides a forum for the publication of original research papers, short communications, and critical reviews in all branches of pure and applied analytical chemistry. Papers are evaluated based on established guidelines, including the fundamental nature of the study, scientific novelty, substantial improvement or advantage over existing technology or methods, and demonstrated analytical applicability. Original research papers on fundamental studies, and on novel sensor and instrumentation developments, are encouraged. Novel or improved applications in areas such as clinical and biological chemistry, environmental analysis, geochemistry, materials science and engineering, and analytical platforms for omics development are welcome. Analytical performance of methods should be determined, including interference and matrix effects, and methods should be validated by comparison with a standard method, or analysis of a certified reference material. Simple spiking recoveries may not be sufficient. The developed method should especially comprise information on selectivity, sensitivity, detection limits, accuracy, and reliability. However, applying official validation or robustness studies to a routine method or technique does not necessarily constitute novelty. Proper statistical treatment of the data should be provided. Relevant literature should be cited, including related publications by the authors, and authors should discuss how their proposed methodology compares with previously reported methods.
