Adsorption of anionic surfactant at the electrode–NaClO4 solution interface
ABSTRACT Adsorption of 1-decanesulfonic acid at the electrode-NaClO4 solution interface was determined by double-layer differential capacity measurements. At potentials less than -1,200 mV, the adsorption of the anionic surfactant on the electrode does not occur. Low concentrations of the anionic surfactant (below cmc) causes slight changes in the zero charge potential, Ez, and the surface tens...
متن کاملEffect of cationic surfactant on the adsorption characteristics of anionic surfactant on cellulose surface
Adsorption kinetics and equilibrium studies of sodium dodecylbenzenesulfonate (NaDBS) on cellulosic surface are investigated. Modifications in adsorption induced by cationic surfactant cetyltrimethylammonium bromide (CTAB) are studied. It is concluded that the rate of adsorption and the amount of adsorption are increased. Importance of these observations in detergency is indicated.
متن کاملAn Experimental Study of Surfactant Alternating CO2 Injection for Enhanced Oil Recovery of Carbonated Reservoir
Core flooding experiments were conducted with the objective of evaluating near miscible surfactant alternating CO2 injection and the effect of surfactant concentrations on gas-oil and water displacements in porous media. The core samples were provided from a low permeability mixed wet oil reservoir at 156 °F and 1900 psia. In addition, very few studies of surfactant adsorption on car...
متن کاملMixed solutions of anionic and zwitterionic surfactant (Betaine): surface-tension isotherms, adsorption, and relaxation kinetics.
Here, we present experimental surface-tension isotherms of mixed solutions of two surfactants, sodium dodecyl sulfate (SDS) and cocoamidopropyl betaine (Betaine), measured by means of the Wilhelmy plate method. The kinetics of surface-tension relaxation exhibits two characteristic time scales, which have been distinguished to determine correctly the equilibrium surface tension. The transition f...
متن کاملSurfactant Stabilized Nanoemulsion: Characterization and Application in Enhanced Oil Recovery
Nanoemulsions are a class of emulsions with a droplet size in the range of 50–500 nm and have attracted a great deal of attention in recent years because it is unique characteristics. The physicochemical properties of nanoemulsion suggests that it can be successfully used to recover the residual oil which is trapped in the fine pore of reservoir rock by capillary forces after primary and second...
