Electron Microscope Observations of Chromium Hydroxide-Induced Montmorillonite Microclusters

Cobalt hydroxide colloidal particles precipitation on nanoclay layers for the formation of novel nanocomposites of carbon nanotubes/nanoclay

“…Additionally, the brucite ''islands'' formed initially can retard further diffusion of the basic monomers and small polymers. This mechanism has already been proven for other metal hydroxides, such as Al(OH) 3 , Fe(OH) 3 , and Cr(OH) 3 [12,14,17]. We believe that the above adsorption mechanism can also be applied in the present investigation.…”

“…In the catalytic area, clay mineral intercalated Ag nanoparticles [3,7], Cu nanoparticles [2], and titanium dioxide nanoparticles [8] have all been found to display improved photocatalytic properties. However, despite these researches, few works have been carried out in the association of metal hydroxide with clay [12][13][14][15][16][17].…”

Changes in Acidity of Fe-Pillared/Delaminated Smectites on Heat Treatment

“…The removal of heavy metal ions such as cobalt, acidity is given in terms of a pK a distribution of surface nickel, or chromium from natural water and waste water species. The pK a values obtained for our sorbents are comstreams is one of the environmentally important applications pared to pK a values of iron complexes present in a solution of these materials (1)(2)(3)(4). Sorption capacity of clays is rewhich are described in the literature (13,14).…”

A Study of Acidity and Structure of Hydroxy-Cr Intercalated Bentonites

“…The pK a distributions obtained from surface of clays. Dubbin and Goh (2,4) reported the amount potentiometric titration data have been recently reported in of chromium adsorbed in clays to be up to Ç1000 cmol(/)/ the literature for various solids (19)(20)(21)(22)(23)(24)(25)(26). The pK a 's obtained kg.…”
