The concentrations of nitrate in standard water samples and natural water samples with different frozen time were measured by continuous flow analyzer.Results showed that the nitrate concentration of standard water samples were basically correspondent with the original values during the experiment.For samples of natural water,with the frozen time of 2 days,the nitrate concentrations were higher than the original values;and they were lower than the original values with the longer frozen time in the next 2 days.
