5 Questions
What is the working pH range for the Cr(VI)-mediated Fenton oxidation?
3−10
What is the main advantage of replacing Fe(II) with Cr(VI) in the Fenton-like oxidation process?
Elimination of limitations like narrow working pH range and iron sludge formation
How is the Fenton-like oxidation of Methylene Blue (MB) dye achieved in the study?
By generating HO radicals through the disproportionation of chromium-coordinated peroxo complexes
What confirms the complete mineralization of the dye in the study?
Observing the decay of MB peaks by a spectrophotometer and cyclic voltammetry
What is a notable feature regarding sludge formation in the Cr(VI)-mediated Fenton oxidation process?
No sludge formation takes place up to four cycles as the oxidation remains in the pure solution phase
Test your knowledge about Cr(VI)-mediated homogeneous Fenton oxidation and its application in the decolorization of methylene blue dye. Explore the sludge-free process pertinent to a wide pH range discussed in the ACS Omega article.
