Abstract

Abstract Interfacial pressure vs concentration curves of dinonylnaphthalenesulfonic acid (HD) at the toluene-HClO 4 water interface have allowed to calculate the c.m.c. of HD in toluene, the free energy of micelle formation, a rough estimate of its cross section at the interface and its degree of polymerization. The last one has been also evaluated through distribution measurements of Eu 3+. The results obtained with the two techniques have been found in good agreement.
