A method that uses the intensity of the absorption of the oxidized cell uloses at 5.S microns as a measure of their carboxyl content is described. The analyses are canied out on mineral oil slurries of 1:1 mixtures of fine ly divided polystyrene and cellulose. The absorption of the polystyrene at 6.2 microns is used as a reference band, t hus obviating the necessity of accurately controlling the thickness of the absorption cell. The method gives results that agree fairly well with those obtained by the calcium acetate method and can be used to detect as little as 0.1 millimole of carboxyl per gram of cellulose.
