Groundwater chromate removal by autotrophic sulfur disproportionation

open access: yesEnvironmental Science and Ecotechnology
Chromate [Cr(VI)] contamination in groundwater is a global environmental challenge. Traditional elemental sulfur-based biotechnologies for Cr(VI) removal depend heavily on the synthesis of dissolved organic carbon to fuel heterotrophic Cr(VI) reduction ...

Photo-enhancement of Cr(VI) reduction by fungal biomass of Neurospora crassa

open access: yes, 2012
Various organisms such as fungus are capable of reducing Cr(VI) to less toxic Cr(III). However, light-induced Cr(VI) reduction by fungus is less reported and needs to be explored since anthropogenic or natural activities may bring these two reactants ...

Cr(VI) reduction by cell-free extract of thermophillic Bacillus fusiformis NTR9 [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2013
Residual chromium compounds in discharged effluents is a serious problem, due to hexavalent chromium or chromate[Cr(VI)] being extremely toxic and showing mutagenic and carcinogenic effects on biological systems.

Isotopic fractionation of chromium and uranium during Cr(VI) reduction by ascorbate and U(VI) reduction by sulfide [PDF]

open access: yes, 2014
Chromium and uranium naturally occur in a variety of Earth’s waters. Both elements can undergo valence state changes at surface conditions which control their chemical behavior in near surface settings.

Electrochemical Cr(VI) reduction using a sacrificial Fe anode: Impacts of solution chemistry and stoichiometry

open access: yes, 2017
A systematic investigation of Cr(VI) reduction using electrochemical reduction revealed that the Cr(VI) reduction was extremely fast with reaction kinetics limited by the anodic generation of Fe(II). The Cr(VI) reduction rate increased with decreasing pH

Enhanced reduction of Cr(VI) in UV/EKR system by organic acids:Focus on Cr(VI) desorption and Fe(III) catalysis

open access: yes
Reducing highly toxic and mobile Cr(VI) to environmentally less hazardous Cr(III) is vital research for remediating Cr-contaminated soil. In this study, a UV/EKR system, which combined electrokinetic remediation (EKR) technology with ultraviolet (UV ...
