چکیده انگلیسی
The adsorption of sodium dodecyl sulfate (SDS) and sodium dodecyl benzenesulfonate (SDBS) on poly(vinyl chloride) (PVC) latex particles was investigated. Conductometric titrations were performed to determine the area per surfactant molecule at various temperatures (20-50 °C) and the adsorption isotherms of both emulsifiers were determined at 20 °C from surface tension titration curves. The adsorption data show some deviation with respect to the Langmuir isotherm due to their slight S-shape. The data can nevertheless be fitted very well with a limiting form of the general adsorption equation proposed by Zhu and Gu [B.-Y. Zhu, T. Gu, Adv. Colloid Interface Sci. 37 (1991) 1].
