Physicochemical characteristics and suitability of curative pastes made of Tunisian clay minerals and thermal waters for use in pelotherapy

This study presents the physicochemical characteristics of peloids prepared from two Tunisian clays, CZ (clay from the region of Zaghouan) and CS (from the region of Siliana), and two thermal mineral waters. The samples were analyzed by several physicochemical techniques: X-ray diffraction, chemical composition (major and minor elements), grain-size distribution, cation-exchange capacity, plasticity index, and thermal properties (cooling kinetic). The results prove that the two clays are suitable for use in Tunisian spa with differences in their characteristics, especially with regard to their composition, plasticity, grain size distribution, and thermal properties.
