Aqueous solubility speciation of Cr(VI) in ferrochrome bag filter dust
(North-West University, 2015)The production of ferrochrome (FeCr) from chromite ore is a reducing process, whereby the Cr(III) and Fe(II) in the ore are reduced to metallic chromium (Cr) and iron (Fe) in the final product. FeCr is mostly used for the ... -
Assessment of atmospheric trace metals and water soluble ionic species at two regional background sites
(North-West University (South Africa), Potchefstroom Campus, 2015)In this study, atmospheric trace metals and water soluble ionic species were investigated. Five research articles are presented. In the first two articles specific trace metals species, i.e. mercury and hexavalent chromium, ... -
Chromium dust deposition on plant leaves in Sekhukhuneland, South Africa, and the importance of leaf traits
(North-West University (South Africa), 2021)Chromium (Cr) is a hazardous heavy metal and its highest oxidized state, hexavalent Cr (Cr(VI)), can be carcinogenic. The ultramafic outcrops of Sekhukhuneland, South Africa, which belong to the Rustenburg Layered Suite, ... -
Iron nanoparticles derived from rooibos tea extract supported polymer for Cr⁶⁺ removal
(North-West University (South Africa), 2019)Deterioration of water quality due to the presence of toxic heavy metals in environmental water resources introduced by industrial pollution is a serious matter of concern today. Only around 20% of the global wastewater ...
