Radiometric and spectrophotometric studies of the behavior of chromium(VI) oxide in concentrated perchloric acid
(R Oldenbourg VerlagMunchenAlemanha, 1997)
Characterization of silica supported chromium complexes
(Planta Piloto de Ingeniería Química, 2000-03)
The Cr/SiO2 catalysts were prepared via the deposition of mononuclear and binuclear chromium (III) ammine complexes on silica. The influence of chromium loading and calcination temperatura upon the type of species formed ...
Adsorption of chromium(VI) by titanium(IV) oxide coated on a silica gel surface
(Royal Soc Chemistry, 1991-03-01)
Titanium(IV) oxide, coated on the surface of silica gel (surface area, 308 m2 g-1; amount of Ti(IV) per gram of modified silica gel, 1.8 x 10(-3) mol), was used to adsorb CrO4(2-) ions from acidic solutions. The exchange ...

Chromium retention properties of N-alkyl quaternized poly(4-vinylpyridine)
(2009)
The ability of solid N-alkyl quaternized poly(4-vinylpyridine) with hexyl, octyl and decyl bromide for the retention of chromate and dichromate forms of Cr(VI) in aqueous solutions is studied. The retention of Cr(VI) was ...
