TL;DR: The sorption capacities of commercial developed carbons and other low cost sorbents for chromium remediation are provided, and particular attention is paid to comparing the sorption efficiency and capacities of commercially available activated carbons to otherLow cost alternatives.
1,611 citations
TL;DR: This review describes the environmental implications of Cr(VI) presence in aqueous solutions, the chemical species that could be present and then the technologies available to efficiently reduce hexavalent chromium.
1,063 citations
TL;DR: Competition from common coexisting ions such as Na+, Ca2+, Mg2+, Cu2+, Ni2+, NO3-, and Cl- was ignorable, which illustrated the selective adsorption of Cr(VI) from wastewater.
949 citations
TL;DR: The chemical/biological remediation processes for Cr(VI) and their efficiency have been summarised in some detail and the interaction of chromium with various microbial/bacterial strains isolated and their reduction capacity towards Cr( VI) are also discussed.
841 citations
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.
