摘要：A simple and rapid method for the determination of nitrate in vegetables by high-performance liquid chromatography was investigated. Nitrate was extracted with distilled water from vegetable samples. The sample solution was injected on a "Zipax"SAX column, a pellicular type anion exchange column, and eluted with 0.05M potassium dihydrogen phosphate solution. The eluent was monitored with a ultraviolet detector at a wavelength of 210 nm. The time required for the analysis was 10 min. The recovery of nitrate from ten kinds of vegetables was 86.0-102.0%.
