Chromium has long been recognized as a toxic, mutagenic and carcinogenic metal. It is toxic to microorganism, plants, animals and humans. Chromium exists in environment in two stable forms: Cr(VI) and Cr(III). Cr(III) is less toxic and insoluble, while Cr(VI) is extremely toxic and highly soluble. Chromium is used in many industrial applications, but it poses a threat to local environment.
Jul 05, 2019· Chromium exists in several oxidation states, but the most stable and common forms are Cr(0), trivalent Cr(III), and hexavalent Cr(VI) species, and later being is considered most toxic [3,5]. In plants, pathway of Cr uptake is not yet clearly understood. Being a nonessential element, Cr does not have any specific uptake mechanism.
utilization for fluidized process due to abrasive motion of the ZVI. In this study Fe2+ was considered as an indicator for complete reduction from Cr(VI) to Cr(III) [16]. In the present study an Electroplating unit employing chrome and bronze plating was selected for process evaluation, removal of copper and chromium from wastewater
Chrome plating (less commonly chromium plating), often referred to simply as chrome, is a technique of electroplating a thin layer of chromium onto a metal object. The chromed layer can be decorative, provide corrosion resistance, ease cleaning procedures, or increase surface hardness. Sometimes, a less expensive imitator of chrome may be used for aesthetic purposes.

Chromium is mined in different countries around the world (such as South Africa, Zimbabwe, Finland, India, Kazakihstan and the Philippines) as the naturally occurring form, chromate ore (FeCr 2 O 4).Chromium is unstable in an oxygenated environment and, when exposed to air, immediately produces an oxide layer which is impermeable to further oxygen contamination.
Chromium (Cr) is a naturally occurring element found in rocks, animals, plants, and soil, predominantly in its insoluble trivalent form [Cr(III)]. Intense industrialization and other anthropogenic activities have led to the global occurrence of soluble Cr(VI), which is readily leached from soil to groundwater or surface water, in concentrations ...
Moreover, chromium-6 is a hazardous pollutant that can cause kidney disorders, cancers and various biotic disturbances. Water hyacinth came to the rescue at Sukinda Chromite mines to remove hexavalent chromium by the phytoremediation process! The plant was powdered and mixed with wastewater.
Chromium is a chemical element with the symbol Cr and atomic number 24. It is the first element in group 6.It is a steely-grey, lustrous, hard and brittle transition metal. Chromium is the main additive in stainless steel, to which it adds anti-corrosive properties.Chromium is also highly valued as a metal that is able to be highly polished while resisting tarnishing.
Chromium (Cr) is known to be a human carcinogen. 6 It is a naturally occurring element found in rocks, soils, and volcanic dust. Chromium is also found in plant and animal bodies as a trace metal, which means that small quantities of chromium are necessary for growth of living organisms but that excessive amounts can be extremely toxic to them.
