In order to investigate the effect of alkyl chain length and builder on adsorption, the adsorption isotherms of linear alkylbenzene sulfonate from aqueous solution on carbon black were determined at 30°C, The adsorption isotherms were fitted to a Langmuir type equation. The amount of saturated adsorption and equilibrium constant which characterize the adsorption were determined by Langmuir plot. The saturated amount depended upon the builder added, but did not upon alkyl chain length. On the other hand, equilibrium constant were markedly affected by alkyl chain length and the builder added. Authers also investigated the correlation between the adsorption of surface active agent on carbon black and the deposition phenomena of carbon black on textile fibers in surface active agent solution, but could not obtain a clear conclusion.
