Results presented in this paper consider research on the influence of the presence of surfactants (cationic CTAB, anionic SDS) on adsorption of poly(acrylic acid) (PAA) at the titanium dioxide/solution interface. Research was carried out as a function of concentration of surfactants and the way of introduction of reagents to measured mixtures (PAA-CTAB-TiO2-NaCl and PAA-SDS-TiO2-NaCl). In order to compare obtained results of adsorption amount of PAA in mixed systems, measurements of adsorption amount of PAA on titanium dioxide without surfactant addition were also conducted. Observed changes in adsorption amount in the presence of surfactant are a result of an emerging complex polymer-surfactant and competitive adsorption of the two components on the TiO2 surface.
