Removal of chromium (VI) ions from aqueous solutions by using Turkish montmorillonite clay: effect of activation and modification This study provides information on the Cr(VI) adsorption potential of Turkish (Mihalıççık region) montmorillonite clay as an abundant, cost-effective and untried material. Batch adsorption trials of chromium were performed to investigate the effects of pH, contact time, and initial metal ion concent Desalination 244 (2009)
Sorption of chromium (III) from aqueous solution using bentonitic clay A local clay from Jebel Chakir (northwest of Tunis, Tunisia, North Africa) has been characterized. The mineralogical and chemical compositions of the materials were determined by X-ray diffraction (XRD), infrared spectroscopy (IR) and by the inductively coupled plasma technique (ICP). The cation exc Desalination 248 (2009)
A study of the binding strength and thermodynamic aspects of cadmium and lead ions with natural silicate minerals in aqueous solutions Batch sorption experiments were conducted with cadmium and lead ions at low equilibrium concentrations in 0.01 M of NaNO3 onto Petra clay in single component systems. The equilibrium isotherms were determined at pH 6 under constant ionic strength and at different temperatures. The experimental data Desalination 242 (2009)
Clay plane membranes: development and characterization Plane supports based on clay are elaborate by using organic additives like agents of porosity. They are then characterized by various techniques: mercury porosimetry, nitrogen adsorption/desorption, electronic scan microscopy. According to the nature of clay, the nature of the organic additive and t Desalination 221 (2008)
Study of performances of ceramic microfiltration membrane from Tunisian clay applied to cuttlefish effluents treatment Microfiltration membrane is increasingly used in wastewater treatment to produce a higer quality effluent. In this study a microfiltration membrane from Tunisian clay (JM18/SI2) was used to treat cuttlefish effluents generated from the conditioning (freezing and washing) seawater food industry which Desalination 200 (2006)
Purification of water effluent from a milk factory by ultrafiltration using Algerian clay support A milk factory sited at Boudouaou (40 km from Algiers) rejects a great quantity of effluent which contains soft whey. 8,000 l are treated twice a week and are rejected into a river which supplies drinking water to the town population. Some analyses have shown an increase in the water acidity and bot Desalination 167 (2004)
Thermodynamics of water sorption in clay Experimental data on desorption isotherms of three types of clay at different temperatures (40, 50 and 60°C) were determined using a static method.
