Nanomaterials for subsurface application: study of particles retention in porous media

Abstract The ability to transport nanoparticles through porous media has interesting engineering applications, notably in reservoir capacity exploration and soil remediation. A series of core-flooding experiments were conducted for quantitative analysis functionalized TiO 2 various including calcite, dolomite, silica, limestone rocks. adsorption surfactants on the rock surface nanoparticle retention pore walls evaluated by chemical oxygen demand (COD) UV–Vis spectroscopy. By applying nanoparticles, 49.3 68.0 wt.% surfactant reduction observed dolomite silica rock, respectively. Not surprisingly, value deposition rocks was near zero, implying that is proportional deposition. On other hand, increased types presence nanoparticles. 5.5, 13.5, 22.4 estimated black red limestone, making a connection between physicochemical properties rates, we concluded roughness significant influence mechanical trapping pore-throats.
