| Abstract: | The way is probed of determining the total nitrogen in the surface waterby using the potassium supersulphate oxidization-resorcinol, spectrophoto-metric method, with the method for determination of nitric acid ion in thewater by resorcino1 as a reference. This method has been proved to be quiteprecise a11d accurate. The minimum accuracy is O. 08 mg/l. |
