Abstract

An automated chromatographic system for the determination of nitrate in lake water has been prepared in conjunction with a personal computer. The calibration curve in the concentration range of 0−200 ppb nitrate-nitrogen was linear. The percent of standard deviation was 0.45% for 20 measurements of 40 ppb nitrate-nitrogen solutions. The correlation coefficient between the results obtained by the proposed method and the Autoanalyzer method for 16 samples was 0.990. Nitrate at parts per billion level could be determined within 10 min. Moreover, a quantitative range of nitrate measurement can be selected by changing the enrichment period of the sample solution. The results of continuous measurement of nitrate at Lake Biwa are reported in this paper.
