Über Sorptionsvorgänge von Carbonsäuren an Haarkeratin

The Sorption Process of Carboxylic Acids on Hair Keratin Methods for the measurement of adsorption of carboxylic acids by hair keratin were worked out. The different methods show good agreement in their results. The adsorption of monochloroacetic acid was determined in relation to its concentration, time of action and pH value. Also the adsorption of homologous and variedly substituted carboxylic acids from aqueous as well as absolute propanol solutions was compared to each other. For the adsorption of carboxylic acids by hair keratin, the dissociation, chain length, substitution and solvent are of utmost importance.
