13 p, 809.1 KB Removal of Hg(II) from an aqueous medium by adsorption onto natural and alkyl-amine modified Brazilian bentonite / Guerra, Denis L. (Universidade Federal de Mato Grosso) ; Silva, Emiliano M. (Universidade Federal de Mato Grosso) ; Lara, Weber (Universidade Federal de Mato Grosso) ; Batista, Adriano C. (Universidade Estadual do Norte Fluminense)
Mercury ion removal from waste-waters has been the subject of extensive research. The aim of the present investigation was to report the incorporation of the n-alkylamine molecules onto a bentonite surface and the capacities of these new chelating moieties on this modified bentonite surface for mercury removal from water. [...]

Faculty of Geodesy and Cartography) ; Skiba, Stefan (Jagiellonian University. Institute of Geography and Spatial Management) ; Skiba, Michal (Jagiellonian University. Institute of Geological Sciences) ; Šegvić, Branimir (Technische Universität Darmstadt. Institute of Applied Geosciences)
Intense mineral transformations that produce acid soils from weathering zones of pyritebearing rocks, including alterations of layer silicates, are of critical importance to agricultural andenvironmental interests in various regions of the world. [...]

9 p, 458.2 KB Illite from Muloorina, South Australia / Eggleton, Richard A. (Australian National University. Research School of Earth Sciences) ; Gerald, John Fitz (Australian National University. Research School of Earth Sciences)
Illite from Muloorina, just south of Lake Eyre in South Australia, is commonly used as a standard ferric iron-bearing illite which has a cation exchange capacity (CEC) of ~22 meq/100 g, too high a value for this clay to conform to the most recent conclusions about illite composition. [...]

9 p, 591.8 KB Adsorption of neutral red dye from an aqueous solution onto natural sepiolite using full factorial design / Çoruh, Semra (Ondokuz Mayis University. Department of Environmental Engineering) ; Geyikçi, Feza (Ondokuz Mayis University. Department of Chemical Engineering) ; Elevli, Sermin (Ondokuz Mayis University. Department of Industrial Engineering)
The main objective of factorial design is to construct an empirical model to understand complex phenomena such as a purification process up to a given level of accuracy. The present study aimed to investigate the adsorption of Neutral Red dye (NR) from an aqueous solution onto sepiolite using 2 full factorial design. [...]

14 p, 1.5 MB Hydration behavior of MX80 bentonite in a confined-volume system : Implications for backfill design / Perdrial, Julia N. (University of Arizona. Department of Soil, Water and Environmental Science) ; Warr, Laurence N. (Ernst-Moritz-Arndt Universität. Institut für Geographie und Geologie)
Bentonites are considered suitable backfill material for planned underground nuclear-waste repositories because of an inherent capacity to self-seal and retain contaminants when hydrated. Barrier effectiveness, however, depends on the physical properties of bentonite after placement in a repository site, where hydration state and bulk density can vary. [...]
