Abstract: The critical micelle activities (cma) of the mixed systems of sodium dodecylsul-fate-hexylpyridinehydrobromate have been determined by the drop-volume method under different ionic strengths (25 ℃). A formula to estimate the effect of inorganic salt electrolyte on the cma has been proposed.

Key words: Surface activity, Critical micelle activity, Counterion bonding degree, Surfactant
