Remediation technologies for heavy metal contaminated groundwater.
TL;DR: Thirty five approaches for groundwater treatment have been reviewed and classified under three large categories viz chemical, biochemical/biological/biosorption and physico-chemical treatment processes for a better understanding of each category.

Nanoscale zero valent iron and bimetallic particles for contaminated site remediation
Denis M. O'Carroll,Denis M. O'Carroll,Brent E. Sleep,Magdalena M. Krol,Hardiljeet K. Boparai,C. M. Kocur +5 more
TL;DR: The use of nano zero valent iron (nZVI) for groundwater remediation has been investigated for its potential to reduce subsurface contaminants such as PCBs, chlorinated solvents, and heavy metals.
Journal ArticleDOI
Kinetics of nitrate, nitrite, and Cr(VI) reduction by iron metal.
TL;DR: The kinetics of nitrate, nitrite, and Cr(VI) reduction by three types of iron metal (Fe0) were studied in batch reactors for a range of Fe0 surface area concentrations and solution pH values, indicating that pH was primarily responsible for the differences in rate.
Journal ArticleDOI
Passive treatment of acid mine drainage in bioreactors using sulfate-reducing bacteria: critical review and research needs.
TL;DR: Critical parameters for design and long-term operation of sulfate-reducing passive bioreactors, and several studies conducted to find the best mixture of natural organic substrates for SRB are reviewed.

In-Situ Remediation of Cr(VI)-Contaminated Groundwater Using Permeable Reactive Walls: Laboratory Studies
TL;DR: In this article, four types of Fe-bearing solids, siderite, pyrite, coarse-grained elemental iron, coarsegrained Fe0, and finegrained fine grained Fe 0, were assessed for their ability to remove dissolved Cr(VI) from solution at flow rates typical of those encountered at sites of remediation.

Processes affecting the remediation of chromium-contaminated sites.
Carl D. Palmer,Paul R. Wittbrodt +1 more
TL;DR: Knowing the processes that control the migration and transformation of chromium is important in developing and selecting effective, cost-efficient remediation designs for chromium-contaminated sites.

Coupled Iron Corrosion and Chromate Reduction: Mechanisms for Subsurface Remediation
TL;DR: A cyclic, multiple reaction electrochemical corrosion mechanism, enhanced by the development of an electrical double-layer analogue, is proposed to explain the differing iron reactivities and aquifer material effects.

Zero-valent iron for the in situ remediation of selected metals in groundwater
TL;DR: In this paper, a series of kinetic-batch studies was conducted to determine the capability of zero-valent iron (Fe0) to remove a wide range of highly mobile contaminants in groundwater.
