The structure and features of surfaces of clay minerals (kaolin, montmorillonite, etc) have an important scientific and practical value. On the surface the interrelation of processes at electronic, atomic and molecular levels is realized. Availability of mineral surface to external influences opens wide scientific and technical opportunities of use of the surface phenomena, so the research of c...
The mechanical response of clay mass can be significantly affected by the distribution and arrangement of the particles and the interaction between them. A series of compression and extension tests under drained and undrained conditions were performed on normally consolidated and heavily over-consolidated clay specimens with different microfabric. The experimental data indicates strong influenc...
Geophagy, although often seen in rural or preindustrial settings among children and pregnant women [11] is not limited to any particular age or time [12]. Clay consumption has been reported to be associated with pregnancy, and some women eat clay to eliminate nausea [13]. Report says that this process may also result in the absorption of dangerous toxins and eggs of parasites that may have been...
Isolated patches of white clay occurring in the terminal moraine of Long Island, Staten fsland, and southern New Jersey have been mentioned in a number of geologic descriptions. Such an occurrence was recently encountered during excavation for a building site and samples were submitted to the mineralogical laboratory of Columbia University for identification by Messrs. Schoonmaker and Kirkman. ...
The S ile Region contains discontinuous, cyclic, thin coal beds and industrial clay deposits that were accumulated in lacustrine basins which received extensive volcanoclastic sediments due to transport of highly weathered calc-alkaline volcanic rocks. The Sülüklü area has the largest kaolin deposit in this region. Cyclic kaolinization depended on the degree of leaching of Si and alkalis in cyc...
The zeolite type prepared from kaolin depends on the mode of fusion clay with Y and X generated, respectively, partial or full fusion. Wet mixing NaOH followed by dry optimises formation X.
The aim of this work was the fabrication and the characterization of mixed matrix membranes (MMMs) for arsenic (As) removal from water. Membrane separation was combined with an adsorption process by incorporating the kaolin (KT2) Algerian natural clay in polymeric membranes. The effects of casting solution composition was explored using different amounts of polyethersufone (PES) as a polymer, p...
