Research ArticleOpen accessIn the keywordsCharacterization of Egyptian Smectitic Clay Deposits by Methylene Blue AdsorptionSalwa D. Abayazeed, Essam El-HinnawiProblem statement: The characterization of smectitic clays has been traditionally made using physical and chemical methods which are time-consuming and require costly equipment. Adsorption of methylene blue by these clays has been introduced as a quick and cheap method for the estimation of cation exchange capacity and surface area. Therefore, the aim of the present study was to test the … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 11 Oct 2011 · 7,504 accessesView PDFCite
Research ArticleOpen accessIn the abstractSIMULTANEOUS OPTIMISATION OF DRYING PARAMETERS OF CERAMIC BODIESSalah Mahmoudi, Ezzeddine Srasra, Fouad ZargouniThis study deals with the mineralogical, physico-chemical and geotechnical analyses of representative Aptian clays in the north-east of Tunisia. X-ray diffraction reveals a predominance of illite (50-60 wt.%) associated to kaolinite and interstratified illite/smectite. The accessory minerals detected in raw materials are quartz, calcite and Na-feldspar. The average amounts of silica, alumina and alkalis are 52, 20 and 3.5 wt.%, … …Current Research in Geoscience, Vol. 4, Issue 1 · 1 Jul 2014 · 6,991 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeavy Metal Mobility in Polluted Soils: Effect of Different TreatmentsMarta Susana Zubillaga, Emiliano Bressan, Raúl Silvio LavadoThe effects of biosolid compost and phytoremediation applied on the leaching of cadmium, copper, lead and zinc, through the different horizons of a superficially polluted soil were determined. The soil was from the Province of Buenos Aires, Argentina. It was contaminated with cadmium copper, lead and zinc. Leaching columns were used with three different horizons: A: 0.12 m A horizon, … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 7,132 accessesView PDFCite
