Abstract

Abstract Fe 3+ Fe 2+ ratios and total iron contents at the interface of clay liner and plastic liner in a composite basal lining system were determined by chemical analysis and Mössbauer spectroscopy. The results prove that a reducing environment is developed at the interface. Hence the physico-chemical properties of the clay are expected to change.
