Acid activation increases the protonated species on a kaolinite surface at the expense of coordinately bound NH(3) entities. The presence of NH(4)(-) ions on an activated sample is not proof of the presence of protonic ...
Phenanthroline Cu(II)-bentonite composite characterization

Tabak, A; Afsin, B; Aygun, SF; Icbudak, H (Springer, 2005)

The penetration of the phenanthroline ligand into the interlayer space of the Cu-bentonite results in the formation of Cu(Phen)(3)-bentonite composite. The expansion of the d(001), basal spacing of the Cu-Bent from 14.24 ...
