ABSTRACT The adsorption behavior of polyvinyl alcohol (PVA) on the CaCO 3 /solution interface under the influence of sodium oleate (SOl) interaction was investigated by the adsorbed amount, FTIR spectra, X-Ray diffraction and zeta potential. Effects of solid to liquid ratio and temperature was also examined. Observed increase of the PVA adsorption in presence of the sodium oleate resulted from a polymer-surfactant complex formation. The surfactant also influences on the structure of the adsorbed pol...
