Point of zero charge for sandstone and carbonate rocks by streaming potential

Point of zero charge (PZC) is defined as the PH at which a solid surface submerged in an electrolyte, exhibits zero net charge. Previous studies have reported different values of PZC for carbonate and sandstone rocks, mostly utilizing the electrophoresis technique. The aim of this study is to invest...
