A comprehensive review on chromium chemistry along with detection, speciation, extraction and remediation of hexavalent chromium in contemporary science and technology
(2021)The presence of hexavalent chromium in our environment is a potential mutagenic hazard for the whole animal and plant kingdom including humans. In the last five decades numerous physico-chemical and bio-chemical mechanisms ... -
Copper foams in water treatment technology: Removal of hexavalent chromium
(2015)Open-cell copper foams were prepared using a space holder technique and tested as filter-beds for the uptake and reduction of Cr(VI) in drinking water. The use of raw cane sugar as a space holder provides an environmentally ... -
Cu-Zn powders as potential Cr(VI) adsorbents for drinking water
(2013)This work examines the possibility of applying CuZn alloys as a reducing medium for the efficient removal of hexavalent chromium from drinking water. In an effort to develop a route for producing powders of CuZn alloys ... -
Hexavalent chromium availability and phytoremediation potential of Cichorium spinosum as affect by manure, zeolite and soil ageing
(2017)Cichorium spinosum (spiny chicory) is a wild edible vegetable, and a possible suitable species for Cr(VI)-phytoremediation. There are three approaches for altering Cr(VI) dynamics: reduction to Cr(III) by organic matter ... -
Modulation of hexavalent chromium toxicity on οriganum vulgare in an acidic soil amended with peat, lime, and zeolite
(2018)Dynamics of chromate (Cr(VI)) in contaminated soils may be modulated by decreasing its phytoavailability via the addition of organic matter-rich amendments, which might accelerate Cr(VI) reduction to inert chromite (Cr(III)) ... -
Occurrence of Cr(VI) in drinking water of Greece and relation to the geological background
(2015)This study provides a survey on potential Cr(VI) exposure attributed to drinking water in Greece. For this reason, a wide sampling and chemical analysis of tap waters from around 600 sites, supplied by groundwater resources, ... -
Optimizing magnetic nanoparticles for drinking water technology: The case of Cr(VI)
(2015)The potential of magnetite nanoparticles to be applied in drinking water treatment for the removal of hexavalent chromium is discussed. In this study, a method for their preparation which combines the use of low-cost iron ... -
Rapid small-scale column tests for Cr(VI) removal by granular magnetite
(2016)This study evaluates the possibility of using magnetite as an adsorbent for the removal of Cr(VI) in a bed column setup under continuous flow conditions. For this purpose, granular magnetite was synthesized on a large scale ...
