Abstract
Three methods of determining nitrate ion concentration in natural waters, namely, the potentiometric method, the spectrophotometric method using sodium salicylate, and the spectrophotometric method using 4-fluorophenol after distillation, are compared. Factors influencing the accuracy and reproducibility of the measurements are determined, and the statistical evaluation of the results obtained is given.
