Removal of Hexavalent Chromium-Contaminated Water and Wastewater: A Review
TL;DR: A survey of removal techniques for Cr(VI)-contaminated aqueous solutions is given in this article, with a particular focus on adsorption, membrane filtration, ion exchange, and electrochemical treatment methods.
Journal ArticleDOI
Removal of heavy metal ions from aqueous solutions using carbon aerogel as an adsorbent.
TL;DR: The results indicate the potential application of this method for effluent treatment in industries and also provide strong evidence to support the adsorption mechanism proposed.
Journal ArticleDOI
Chromium removal by combining the magnetic properties of iron oxide with adsorption properties of carbon nanotubes
TL;DR: The results show that the adsorptions of Cr(III) on the composites is strongly dependent on contact time, agitation speed and pH, in the batch mode; and on flow rate and the bed thickness in the fixed bed mode.

Organic aerogels from the polycondensation of resorcinol with formaldehyde
TL;DR: In this paper, the polycondensation of resorcinol with formaldehyde under alkaline conditions results in the formation of surface functionalized polymer "clusters" which are processed under supercritical conditions to obtain low density, organic aerogels.

Aqueous geochemistry of chromium: A review
TL;DR: In this paper, the authors reviewed the aqueous geochemistry of chromium, especially with reference to the recent work of Rai et al. (report EPRI EA-4544, 1986, Report EPRi EA-5741, 1988), and showed that the chromium content of natural waters is generally low whereas rocks exhibit a wide range of Cr concentrations.
Journal ArticleDOI
Removal of Cr(VI) from aqueous solution by adsorption onto activated carbon.
TL;DR: The adsorption of Cr(VI) was pH dependent and maximum removal was observed in the acidic pH range and was calculated from the Langmuir isotherm.
