| description | The invention discloses a method for quantifying concentrations of nitrite nitrogen and nitrous acid in nitro-oxidant wastewater and relates to the technical field of determination of nitrite nitrogenand nitrous acid in nitro-oxidant wastewater. The method comprises the following steps of respectively establishing standard working curves of nitrate nitrogen and nitrite nitrogen; preparing a nitrooxidant wastewater solution, adding a calibrated hydrogen peroxide reagent, taking a certain amount of the wastewater solution, enabling the concentration of the diluted solution after volume metering to fall in a y1 linear interval, and determining the absorbance value of nitrate nitrogen by adopting a spectrophotometric method; neutralizing and titrating the wastewater solution with a calibrated sodium hydroxide solution until the wastewater solution is neutral or weakly alkaline; in combination with basic theoretical knowledge such as charge conservation and material conservation, relational expressions such as nit |
