Abstract

Effect of aqueous soluble vitamins nicotinic acid, pyridoxine and biologicallyactive ions Co2+, Mn2+, Cu2+ on critical micelle concentration (cmc) of anionic surfactant sodium pentadecylsulfonate, cationic surfactant cetylpyridinium bromideand nonionic surfactant hexadecylpoly[oxyethylene(20)] alcohol(C16A20) in aqueous solutions at 303.15 Kwas studied. It was shown that with increase of vitamins concentration the cmc of studied anionic sodium pentadecylsulfonate increases and cmc of C16A20decreases. In the presence of metal-ions cmc of the studied surfactants decreases.
