The desorption behavior of cationic-nonionic surfactant mixtures, tetradecyltrimethylammonium chloride (TTAC) and pentadecylethoxylated nonyl phenol (NP-15), at the alumina-water interface was studied. It has been found that while nonionic NP-15 itself does not adsorb at alumina-water interface, it

This paper is affectionately dedicated to Professor Walter H. Stockmayer on the occasion of his 80th birthday. The work greatly benefited from the experimental skills of Nathalie Fritz. Publication of this paper was permitted by Ciba-Geigy AG.
Literature data for homologous series of nonionic and ionic surfactants, such as C(n)OH, C(n)EO(m), Tritons, C(n)SO4Na, and C(n)EO(m)SO4Na, were analyzed on the basis of the Frumkin and reorientation models. The thermodynamic quantities obtained from the reorientation model agree best with the exper

Specular neutron reflection has been used to investigate the effects of temperature and added electrolyte on the adsorption of nonionic surfactants and nonionic surfactant mixtures at the air-water interface. For the alkyl poly-oxyethylene oxide nonionic surfactants, C(n)EO(m), the adsorption at the
The simultaneous adsorption of three poly(ethylene oxide) (PEO) with different molecular weights and two cationic surfactants on silica under a constant feed concentration of PEO has been investigated in aqueous solutions. Two cationic surfactants were used; dodecyltrimethylammonium bromide (DTAB) a
