摘要：

Results concerning the single-solute adsorption of two anionic surfactants were presented in a previous paper; this paper deals with their mixtures. Equilibrium adsorption isotherms of mixtures of sodium lauryl sulfate and sodium dodecylbenzene sulfonate in aqueous solution by Amberlite XAD-4 and XAD-7 polymeric resins at 10 and 30-degrees-C have been obtained and are compared to the predictions given by several multicomponent adsorption models that make use of the single solute adsorption data already available. Reasonable agreement has been achieved in some cases, especially when predicting total surfactant adsorption.
