NO CONTENTS SECTION
Spectrophotometric measurement of the yellow-coloured nitrophenol, at a wavelength of about 435 nm, formed after permanganate oxidation of nitrous nitrogen to nitric nitrogen and reaction of the latter with 3,4-xylenol. Applicable to products having an oxides of nitrogen content, expressed as nitrogen, equal to or greater than 0.2 mg/kg. Also for use in the food industry.
