Efficiency of aluminum-pillared montmorillonite on the removal of cesium and copper from aqueous solutions

Investigation of structure and thermal stability of surfactant-modified Al-pillared montmorillonite

“…Because of their large specific surface area, high pore volume, micro-/mesoporosity, and strong surface acidity, PILCs have significant applications in diverse areas [5][6][7][8][9]. For example, they can be used as efficient adsorbents for oxyanionic contaminants [10][11][12] and heavy metals [13,14], and as attractive cracking catalysts for heavy petroleum [1,15,16]. However, PILCs do not efficiently remove the hydrophobic organic compounds from water because of the hydrophilic surface.…”

Adsorption of phenol, phosphate and Cd(II) by inorganic–organic montmorillonites: A comparative study of single and multiple solute

“…The Freundlich model is applicable to multilayer adsorption on heterogeneous surface [33]. The observer better fit of the experimental data with freundlich isotherm can attribute to heterogeneous distribution of active sites on IOMts [33,34]. The adsorption capacities of IOMts toward phosphate increased in the order: C 0.4 -AlPMt < Z 1.0 -AlPMt ≈ Z 0.4 -AlPMt < C 1.0 -AlPMt (Fig.…”

BiVO4/Fe/Mt composite for visible-light-driven degradation of acid red 18

“…Intercalating Mt with various functional intercalants can always increase the basal spacing and specific surface area of Mt, and the reactive sites on Mt as well (Herney-Ramirez et al, 2010). As such, large amounts of Mtbased catalysts have been synthesized by intercalating Mt with various hydroxy-metals (Ai and Hameed, 2011), such as hydroxy-iron intercalated Mt (Fe/Mt) (Feng et al, 2003(Feng et al, , 2004Wu et al, 2009), hydroxyaluminum intercalated Mt (Epstein and Yariv, 2003;Karamanis and Assimakopoulos, 2007), hydroxy-iron-aluminum intercalated Mt (Konstantinou et al, 2000;Carriazo et al, 2003), etc.…”
