“…Compared with the proposed method, a few other analytical methods show lower detection limits. 14,25 However, these methods are very expensive and highly sophisticated. In addition, in gas chromatography and spectrophotometric methods nitrite and nitrate must be derivitized in order to make them suitable for measurements.…”

“…Many methods, including spectrophotometric, 6,7 chromatographic, [8][9][10][11] potentiometric, 12,13 gas chromatographymass spectrometry (GC-MS) and liquid chromatography with fluorescence detection 14 and flow injection analysis [15][16][17] have been reported for the quantitative and qualitative analysis of nitrite and nitrate. Nonetheless, most of these methods suffer from a number of disadvantages, such as highly complication and laborious derivitization, the need for toxic reagents and harmful organic solvents, extensive sample preparation, time-consuming analysis, stability of the colored product formed, etc.…”

Nowadays, nitrite and nitrate ions are analyzed in biological samples using laborious and expensive methods; such as HPLC, CE, MS-MS. In this work, the simultaneous analysis of nitrite and nitrate ions was conducted by electrospray ionization-ion mobility spectrometry (ESI-IMS), without using any complicated or laborious derivitization step. Ion mobility spectrometry with low cost, inexpensive maintenance and very fast analysis makes an attractive technique for the simultaneous determination of these ions in foodstuff and drinking water samples. The analyte interference was systematically investigated for binary mixture analysis. The obtained results provided detection limits of 3.8 and 4.7 μg/L for nitrite and nitrate, respectively. A linear dynamic range of about 2 orders of magnitude, and relative standard deviations below 5% were obtained by the proposed method for the analysis of both ions. Also, the proposed method was used to analyze various real samples of potato and drinking water samples, and the obtained results confirmed the capability of negative ESI-IMS for the simultaneous detection of nitrite and nitrate.

Recebido em 18/7/11; aceito em 14/10/11; publicado na web em 20/1/12An optical chemical sensor for the determination of nitrite based on incorporating methyltrioctylammonium chloride as an anionic exchanger on the triacetylcellulose polymer has been reported. The response of the sensor is based on the redox reaction between nitrite in aqueous solution and iodide adsorbed on sensing membrane using anion exchange phenomena. The sensing membrane reversibly responses to nitrite ion over the range of 6.52×10 -6 -8.70×10 -5 mol L -1 with a detection limit of 6.05×10 -7 mol L -1 (0.03 mg mL -1) and response time of 6 min. The relative standard deviation for eight replicate measurements of 8.70×10-6 and 4.34×10-5mol L -1 of nitrite was 4.4 and 2.5 %, respectively. The sensor was successfully applied for determination of nitrite in food, saliva and water samples.
