..., dolomite, calcite and clay, while Berea sandstone contains over 75 wt% quartz. Herein, the effects of surfactant concentration, surfactant type, temperature, adsorbents and salinity on adsorption density were covered, and the impacts of surfactant concentration and adsorbents were found to be more...

... sandstone or limestone and of an aqueous phase of surfactant in 2% brine. Effects on surfactant adsorption density for different solid to liquid ratios as well as surfactant concentration, rock type and state, and flow conditions are presented. Three systems were used: batch tests on crushed rock...

... concentration range, and that increasing concentration increases adsorption density. There is significant hysteresis between CLS adsorption and desorption isotherms. Increasing flow rate slightly decreased CLS equilibrium adsorption. Increasing both NaCl and CaCl 2 concentrations increased adsorption density...

.... Results show that CD adsorption and desorption onto powdered minerals can be established in one hour. The decreasing order of the surfactant adsorption density onto the five minerals is: montmorillonite, dolomite, kaolinite, silica and calcite. Surfactant adsorption onto the three core systems took...
