Redox potential measurements in a claystone

, 2017
Near-neutral pH and low redox potentials (EH) are considered favorable conditions for immobilization of most of radionuclides in deep repository systems in clay geological formations. The range of pH values in claystones pore waters has been well constrained by collection and analysis of in situ seepage water or water samples squeezed from core samples
