摘要：

An ion interaction chromatography method for the determination of nitrate and nitrite using a reversed-phase C18 column is described. The eluent was 2.0 mM nonylammonium phosphate of pH 6.5 and the UV detection wavelength was 205 nm. For a sample volume of 200 mul detection limits of 2.0 and 1.5 mug/l were obtained for nitrite and nitrate, respectively. The change of the detection wavelength to 190 nm enables also the quantitative detection of chloride. Results obtained for natural waters have been correlated with those obtained using standard spectrophotometric procedures.
