Mechanism of Chromium Separation and Concentration from Tannery Wastewater by Membrane Methods
Membranes, 2023 The article specifies conditions for a nanofiltration process employing a diafiltration method with a constant volume diafiltration (NF-CVD) for exhausted chromium tannery wastewater treatment and describes a mechanism of the examined process carried out

Chromium(III) — chromium(VI) interconversions in seawater [PDF]
Marine Chemistry, 1982 The stable form of dissolved chromium in oxygenated seawater is Cr(VI). But Cr(III)-species are also present at an analytically significant level. It is shown that Cr(III) is oxidized only slowly by dissolved oxygen, and that manganese oxide is a strong catalyst for such oxidation.

Spin density wave dislocation in chromium probed by coherent x-ray diffraction [PDF]
, 2009 We report on the study of a magnetic dislocation in pure chromium. Coherent x-ray diffraction profiles obtained on the incommensurate Spin Density Wave (SDW) reflection are consistent with the presence of a dislocation of the magnetic order, embedded at ...

A Surface Conversion Treatment on a Borided and Cemented Seel Coated with Chromium Filme
Iranian Journal of Materials Science and Engineering, 2021 Coatings based on chromium borides and chromium carbides are commonly employed in applications requiring mechanical performance, such as high hardness and low friction coefficient, as well as corrosion resistance. In this work, we made layers of chromium
