  2. 1 Μαΐ 2021 · Chromium (Cr) is a trace element critical to human health and well-being. In the last few decades, its contamination, especially hexavalent chromium [Cr (VI)] form in both terrestrial and aquatic ecosystems, has amplified as a result of various anthropogenic activities.

  3. ABSTRACT. Cr (VI) compounds find wide uses in the industrial sector, such as wood preservation, tanning, chrome plating, and anticorrosive agents. Several kinds of both natural and industrial factors can lead to Cr (VI) contamination in wastewater.

  4. 6 Μαρ 2023 · Hexavalent chromium (Cr (VI)) is a toxic, mutagenic, teratogenic, and carcinogenic species. Its origin is in industrial activities. Therefore, its effective control is realized on a source basis.

  5. 17 Αυγ 2022 · The major purpose of this article is to provide up-to-date information on extensively used techniques, with an emphasis on the significant issues that are experienced while removing hexavalent chromium from water.

  7. 20 Νοε 2008 · Membrane electrolysis is one of the techniques used for the removal of hexavalent chromium from wastewater. Membrane electrolysis is a chemical process driven by an electrolytic potential. There are two types of cathodes used: a conventional metal cathode (electrowinning) and a high surface area cathode (Janssen and Koene 2002). The oxidation ...
