Abstract
An alternative chromatographic method has been developed to selective and simultaneous detection of nitrite and nitrate in the presence of chloride, based on the use of an anion-exchange polymethacrylate column with 5mM phosphate buffer as eluent and ultraviolet absorbance at 214 nra as detection procedure. The detection limit was 0.5 μg/ml for both anions. This method was shown to be applicable to the analysis of several foodstuffs.Keywords
