| Abstract: | The reaction of magenta and nitrite in sulfuric acid medium was studied.A new method on determination of NO - 2 N was found.The linear range for NO - 2 N is 0～1.6 μg/mL.The apparent molar absorptivity is 1.12×10 4 L/mol·cm.The method has been used to determine surface water and ground water.The results obtained are quite satisfactory and are in agreement with those obtained by the naphthylethy lenediamine hydrochloride colorimetric method. |
