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. [...]

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. [...]
