Chromium (Cr) is a potentially toxic metal originating from natural processes and
anthropogenic activities such as the iron-steel, electroplating, and leather industries, which …

The investigation of a groundwater resource impacted with Cr (VI) requires analysis of
groundwater for Cr (VI) and total Cr. Most notably, Cr (III) is considered to be a trace element …

In recent years, the extensive use of chromium in industrial processes has led to the
promotion of several directives and recommendations by the European Union, that try to limit …

Chromium is introduced into the environment by effluents in several industries. It is important
to control this element since it is both toxic and carcinogenic. As its toxicity depends on its …

Chromium holds a special position among living organisms because depending on its
species it can be either essential or toxic. Cr (VI) even at very low concentrations is harmful …

Numerous critical reviews have evaluated exposure to toxic and carcinogenic hexavalent
chromium (Cr (VI)) from a number of pathways; including workplace air, cement and …

Polyacrylonitrile (PAN) nanofibers functionalized with amine groups (PAN-NH 2) were
prepared using a simple one-step reaction route. The PAN-NH 2 nanofibers were …

The fate of chromium (Cr)–a redox sensitive metal–in surface sediments is closely linked to
early diagenetic processes. This review summarizes the main redox pathways that have …

Chromium (III) is commonly found in large quantities in tannery wastewaters. For this reason,
the recovery of the chromium content of these wastewaters is necessary for environmental …

In the present work, a solid phase extraction system has been proposed for speciation of Cr
(III) and Cr (VI) in the real samples. The procedure based on the adsorption of chromium (III) …
