On the Consequences of Surface Treatment on the Adsorption of Nonionic Surfactants at the Hydrophilic Silica−Solution Interface

Abstract

Specular neutron reflectivity has been used to study the effects of different surface treatments on the adsorption of nonionic surfactants at the hydrophilic silica−solution interface. The consequences of different surface treatments, variations in solution pH, and the exposure to cationic surfactants illustrate the delicate nature of the cooperativity of the adsorption of nonionic surfactants at the liquid−solid interface.
