A novel method has been developed for the photometric determination of nitrogen oxides (NO,; NO and NO, gases). The sample .gas is shaken with an NaOH-alkaline H20, solution in a container so that all the NO, is converted to the NO; form. After decomposition of the H,O, by heating, the colour is dev
