Principle:
Under alkaline medium conditions, potassium persulfate is used as an oxidant to oxidize ammonia nitrogen and nitrite nitrogen in the sample into nitrates, and most of the organic nitrogen compounds in the sample are oxidized into nitrates. NO3- reacts with resorcinol in an acidic environment. Within a certain concentration range, the color depth is proportional to its concentration. The absorbance is measured at a wavelength of 375nm and converted into a total nitrogen concentration value after correction by the calibration curve.
