Open publisher page 0 citations

Abstract

A study on the determination of nitrate was reported in this paper.Analytical method was based on a series of reaction and quantitative relationship between nitrate and urea.A difinite amount of urea was added in the sample to take part in the reaction.Conditions of reaction temperature and reaction time were experimentally optimized.Nitrate was finally determined by titration with slandardized NaOH solution and calculated from the losses of amide nitrogen.
