Adsorption properties of the nanozirconia/anionic

May 01, 2016· The significant PAM adsorption decrease in the anionic surfactant presence at pH 3 is a result of hydrophobic interactions between the main carbon chain of the polymer and hydrocarbon tails of the SDS molecules. This is facilitated by the small dissociation of anionic polyacrylamide. As a result, the polymer–surfactant complexes are formed.
