The properties of ionic micelles of sodium dodecyl polyoxyethylene-2-sulfate in the presence of multivalent ions were investigated by means of Light scattering methods. It was shown that divalent and especially trivalent counterions may lead to dramatic change in the micellar size and shape even at very low ionic strength. This effect is particularly pronounced for trivalent counterions as Al3+. The persistent lengths for some rod-shaped micelles were obtained and the energy of bending of such rods was estimated. The solubilization capacity of sodium dodecyl polyoxyethylene-2-sulfate was shown to be also dependent on the presence of divalent and trivalent ions. it increases with varying the counterion valence from one to thr;ee. The increase of the solubulization capacity of anionic surfactants in the presence of divalent and furthermore trivalent counterions could be of practical importance since it is directly related to the cleaning action of given detergent composition.
