Physicochemical Characterization of Regional Clay: Application to Phenol Adsorption by Abdelouahed Amar, Ilyasse Loulidi, Abderrahim Kali, Fatima Boukhlifi, Chaimaa Hadey, Maria Jabri

“…The chemical analysis of this clay shows that the percentage of silicon and aluminium is quite high, and the percentage of calcium and iron is relatively high, so this material is rich in muscovite, quartz, and calcite. In addition to the presence of titanium dioxide (TiO2), which can give it a property of degradation of organic compounds under ultraviolet light, the pHPZC zero point of our material is 7.4. …”

Material Weakening of Slip Zone Soils Induced by Water Level Fluctuation in the Ancient Landslides of Three Gorges Reservoir by Yu-Yong Jiao, Liang Song, Hui-Ming Tang, Yun-An Li

“…The results indicate that (1) the shearing strength of the slip zone soil dramatically decreased after one wetting-drying cycle and then gradually decreased until reaching a relatively stable state at the fourth cycle; (2) the plasticity index of the slip zone soil varied with increasing number of cycles and a variation process opposite to that of the strength value was observed; and (3) the clay mineral content in the slip zone soil increased and the calcite and quartz contents relatively decreased with increasing number of cycles. …”
