Abstract
The formation of polymer-colloid complexes of chitosan and anionic surfactant—sodium dodecyl sulfate—in water–alcohol mixtures is studied by potentiometry using ion-selective electrodes. The influence of the nature and content of organic cosolvent (methanol, ethanol, and 2-propanol) on the parameters of binding of surfactant with chitosan and the stability of complexes is discussed. The obtained data are analyzed in terms of the model of cooperative binding and pseudophase model. It is shown that addition of 10–20 vol % of ethanol and 2-propanol to aqueous solution intensifies cooperative binding of sodium dodecyl sulfate with chitosan, which leads to the decrease in the critical association concentration and increase in the parameters of cooperativity and stability of complexes.
