Abstract
A method is presented for the simultaneous determination of nitrate and nitrite by high performance liquid chromatography (HPLC) with an anion exchange (Partisil SAX) column, a 0.030 M potassium dihydrogen orthophosphate/phosphoric acid buffer of pH 3.5 mobile phase and UV detector. Without using a preconcentration system the detection limits are 0.2 ng for nitrate and 1 ng for nitrite. A suitable extraction procedure has been established for its application to the analysis of tap water, lettuce and apple tree leaves. The reproducibility of the method, calculated as the relative standard deviations in the optimum range, is always less than 2% for nitrates and 5% for nitrites.
