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
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
