摘要：

The diffusion of water vapour into Bayard montmorillonite and the diffusion/flow of liquid water into Friedland clay were examined with impedance spectroscopy as a first step towards the development of an impedance based sensor system for the in situ monitoring of clay-based barriers for waste containment. By impedance measurements the diffusion of water vapour into clay and the leaching of liquid water through clay barriers can be monitored time-dependently and parameters can be derived from the data that can be used to predict the speed of diffusion/flow through the barrier.
