THE methods available for the quantitative determination of nitric oxide in the absence of air involve differential manometric techniques1,2. This communication describes a direct method for the quantitative determination of the gas. The procedure consists of the oxidation of nitric oxide to nitrite by alkaline permanganate solution. Nitrite is quantitatively recovered after adding alkaline arsenite solution to precipitate the permanganate as insoluble manganese dioxide.
