Radiation and thermal effects on cobalt retention by Mexican aluminosilicates

Enhanced sorption of radiocobalt from water by Bi(III) modified montmorillonite: A novel adsorbent

“…ln q e = ln q max − ˇε 2 (6) where ˇ is the activity coefficient related to the mean sorption energy (mol 2 /kJ 2 ), and ε is the Polanyi potential, which is equal to:…”

“…At present, the most promising and practical approach for removing 60 Co is the addition of non-nutritive adsorptive materials to contaminated water. A variety of natural and synthetic materials such as bentonite [3], MgO, MnO 2 , TiO 2 , SnO [4], ␥-Al 2 O 3 [5], Mexican aluminosilicates [6], chitosan derivatives [7] and carboxylate-functionalized polyacrylamide grafted lignocellulosics [8] have been tested as cobalt adsorbents. Of all the materials, clays have attracted much attention owing to its high cation exchange capacity, large surface area and low cost and ready availability [9].…”

Formaldehyde Adsorption into Clinoptilolite Zeolite Modified with the Addition of Rich Materials and Desorption Performance Using Microwave Heating

“…Previous studies showed that bentonite and granite contain considerable amounts of albite and anorthite, which relatively affect the XRD patterns (Wirsching 1981;Yildiz et al 1999;Yılmaz et al 2007). The albite peak was observed at 2θ = 21.8°, 23.9°, 35.2°, while the anorthite peak was observed at 2θ =14.1°, 28.15°, and 39.2° (Varela et al 2006;Dávila-Rangel et al 2007).…”

Cadmium leaching from thermal treated and gamma irradiated Mexican aluminosilicates

“…In a previous paper we reported the immobilization of cobalt in thermal treated (1100°C) and gamma irradiated aluminosilicates samples, this effect was not observed in the unheated gamma irradiated aluminosilicates [19].…”

“…The purpose of this paper was to determine the stability of Cd 2+ in aluminosilicates after thermal treatment and gamma irradiation, and to compare the results with those obtained in a previous work with Co 2+ exchanged aluminosilicates [19].…”
