“…Most of the methods employed for the determination of nitrite are based on the colorimetric determination of nitrite with diazocoupling reaction. In 1963 Sawicki et al published a review of over 50 spectrophotometric methods for the determination of nitrite 11 . In 1879, Griess proposed the reaction of sulfanilic acid with 1-naphthylamine in the presence of nitrites and sulfuric acid and proposed that it could be used for the determination of nitrites 12 .…”

An inexpensive flow injection analysis system for determining low concentration levels of nitrite employing the Griess reagent spectrophotometric method is reported. The novel photometric detector applied within this manifold is a highly sensitive, low cost, miniaturized light emitting diode (LED) based flow detector. This colorimetric detector employs two LEDs, operating one as a light source and the other as a light detector. The emitter LED is forward biased and the detector reverse biased. The emitter and detector LED had a λ max of 530 nm and 623 nm respectively. The emission spectrum of the emitter LED efficiently overlapped with the absorbance spectrum of 9 µM NO 2 and Griess reagent complex. A simple timer circuit measures the time taken for the photocurrent generated by the emitter LED to discharge the detector LED from 5 V (logic 1) to 1.7 V (logic 0). The Griess reagent method employed for nitrite determination is based on the formation of an azo dye, the intensity of which is directly related to nitrite concentration. The linear range, reproducibility and limit of detection were investigated. Detection limits in the nanomolar range were achieved using the Paired Emitter-Detector Diode (PEDD) flow analysis device. For a comparative study the linear range and limit of detection were also investigated using a platewell reader. Higher sensitivity and improved precision were obtained from the PEDD compared to the commercially available plate well reader.

“…Among many analytical methods proposed for the determination of nitrate and nitrite, a widely used method for analyses of natural water samples is based on the reduction of nitrate to nitrite and a subsequent spectrophotometric determination via the Griess reaction, [1][2][3] which involves the diazotization of sulfanilic acid and successive coupling with 1-naphthylamine. Though numerous modifications have been suggested, primarily based on changing either the reagent being diazotized or coupled, sulfanilamide or sulfanilic acid and N- (1-naphtyl)ethylenediamine are the most popular couples.…”

The determination of nitrite and nitrate in aqueous environmental samples is of considerable interest in research concerning hydrological chemistry, chemical oceanography, and atmospheric chemistry. Nitrate is an essential nutrient which controls the biomass in natural water; the amount also indicates the extent of pollution and eutrophication of the aquatic environment. Nitrite is a nitrogen-cycle intermediate and a useful indicator of the equilibrium state of the oxidative and reductive pathways of the nitrogen cycle. Also, nitric acid and nitrous acid are very important trace constituents of the atmosphere in both the gaseous and particulate phases. Nitric acid is a major NOx sink in photochemical air pollution. Nitrous acid is recognized as a major source of a very reactive hydroxyl radical, which is a key intermediate for all photochemical oxidant formations. These gases and particulates are precursors of acid rain, and are deposited on the ground mainly by wet precipitation, such as rain and snow.Among many analytical methods proposed for the determination of nitrate and nitrite, a widely used method for analyses of natural water samples is based on the reduction of nitrate to nitrite and a subsequent spectrophotometric determination via the Griess reaction, 1-3 which involves the diazotization of sulfanilic acid and successive coupling with 1-naphthylamine. Though numerous modifications have been suggested, primarily based on changing either the reagent being diazotized or coupled, sulfanilamide or sulfanilic acid and N-(1-naphtyl)ethylenediamine are the most popular couples. 4,5 The spectrophotometric method can provide reliable results for natural water samples, but suffers from interferences from suspended and colored substances in the samples. Cox 6 proposed a chemiluminescence analysis technique, which is more highly sensitive and free from these interferences. The technique is based on the chemical reduction of nitrate and nitrite to NO and detection via a chemiluminescence reaction of NO with ozone. Garside 7 first applied this technique to seawater analyses. Braman and Hendrix 8 reported on an application used for environmental water samples. These methods used NaI for reducing nitrite to NO, and iron(II)-molybdate or vanadium(III) for reducing nitrate to NO. The reduction procedures in these methods require highly acidic conditions and/or operation at a relatively high temperature. In the monitoring method of ambient gaseous HNO2, 9 we employed ascorbic acid in a dilute H2SO4 for reducing nitrite to NO. This reagent is easy to handle and the reaction is rapid and quantitative at low nitrite levels. By reducing nitrate to nitrite with an alkaline hydrazine solution, the measurement system was further developed to a gaseous HNO3 monitoring method. 10The coupling of the chemiluminescence detection with a flowinjection technique (FIA) would permit the development of sensitive, precise, rapid, and high throughput methodologies having a wide dynamic range. Aoki and Wakabayashi 11 reported a chemilumine...

“…All in all, the results in Table 2 indicate the usefulness of the proposed procedure in determining trace amounts of nitrite in water samples down to 5 ng/ml. The sensitivity of the method is similar to those employing fluorescent reagents [6,7] and is higher by about one order of magnitude compared with colorimetric methods [1,2]. The precision of determination (r.s.d.…”

“…100 times), thus the reaction progress does not bring about a significant loss of hydrogen peroxide, and the reaction rate on the temporal scale of the experiment is constant and proportional to the initial concentration of H202. The situation is quite different for reaction (1), where the nitrite concentration is comparable to that of thiosulfate (2 x 10-7 M). In the absence of hydrogen peroxide or when the concentration of H202 is low, a significant portion of iodine is produced at the expense of nitrite, so reaction (1) progresses quite rapidly.…”

Sensitive determination of nitrite by means of a Landolt-type reaction in fluorescent aggregates of a binaphthyl-based amphiphile

Abstract.The iodine quenching effect on the fluorescence of a binaphthyl-based amphiphile, CsBNC6 N, was used for monitoring the LandoR-type reaction between nitrite, iodide, and thiosulfate. Due to the possibility of iodine detection in the 10-s-10-7 M range, and to the effective concentration of anionic reagents on the surface of cationic aggregates, the indicator reaction can be monitored using reagents at concentration levels as low as 10-TM. To optimize the analytical system, the effect of pH and reagent concentrations on the rate of indicator reaction were studied. The influence of the matrix of water samples and effect of side-reactions increasing the value of a blank test were examined. A procedure for nitrite determination in water was developed, using the diazo reaction for selective nitrite removal to provide a reference solution, which avoided possible effects of the matrix components. The usefulness of this method was tested by determining trace amounts of nitrite in water samples. The procedure allows determination of nitrite down to 5 ng/ml (detection limit about 2 ng/ml) with r.s.d, of 10% in the 20-250 ng/ml range.Key words: binaphthyl-based amphiphile, fluorimetry, nitrite, Landolt reaction.Nitrogen-containing inorganic compounds, including nitrite, have a strong toxic effect on living organisms. There is a need, therefore, to determine extremely low nitrite levels in food and drinking water samples. Nitrites are most often determined by spectrophotometric methods involving azo dye formation [1, 2-1, as well as by electrochemical [3], chromatographic" [4, 5-], and spectrofluorimetric [6, 7-1 methods. A classical approach of nitrite determination is also known, in which the oxidation of iodide by nitrite in acidic medium is employed [-8-1. 2NO2 + 3I-+ 4H + --~ 2NO + I~-+ 2HaO(1)
