A METHOD FOR DETERMINING AIR-WATER INTERFACIAL AREA IN VARIABLY SATURATED POROUS MEDIA

Materials and methods and scheme of experiment setup prepared in order to obtain all the parameters needed to determine the air-water interfacial area. Results and discussion of surface data measured for different surfactants concentrations. Three glass beads media are used for the calibration of the titration process and the evaluation of areas and surfactant adsorption (monomer sulfonate sodium)compared with NaCl.
