Solvents, in which ionic surfactants do not affect the zeta potential

Abstract

The influence of solvent polarity on adsorption behavior of DOSS (anionic surfactant) has been studied by means of electroacoustic method. DOSS substantially affected the ζ potential of titania and alumina dispersed in methanol and in hydrocarbons. In 1-propanol, 2-propanol, and 1-butanol, which have intermediate polarity between methanol and hydrocarbons, the effect of the ionic surfactant on the ζ potential of solid particles was less significant. © 2009 Elsevier Inc.
