were calculated between 1 conc. and absorption at 420nm: NaNO,; y = 2 2 . 0 ~ (c = 0.9966), HNO,; y = 17.7x-0.53 (c = 0.9997), HzOz; y = 18.Ox-0.20 (c = 0.9991), where x = 1 conc. (mg/50ml), y = absorption x 100, and cis the correlation coefficient. After addition of NH3 (10 % aqueous solution, 5ml in NaNOZ and H,O, experiments, 10ml in HNO, experiment), absorption at 450nm was measured after 10min: NaNO,; y = 45.3~-1.23 (c = 0.9996), HNO,; y = 2 7 . 5 ~ + 0.40 (c = 0.9988), HzOz; decolorization of sample. specific clients.
