A review of the strategies employed to facilitate the detection, determination and monitoring of nitrate and/or nitrite is presented. A concise survey of the literature covering 180 reports submitted over the past decade has been compiled and the relevant analytical parameters (methodology, matrix, detection limits, range, etc.) tabulated. The various advantages/disadvantages and limitations of the...
Normal phase ion-pair high performance liquid chromatography has been used for simultaneous separation of nitrite and nitrate using tetraethylammonium (TEA) + as ion-pairing reagent. The concentration effect of (TEA) + , buffer salt and pH of the eluent on separation is investigated. The UV detector response at various wavelengths has been optimized. The performance of the proposed...
