In fact, Mn3+/Mn5+ oxides are strong oxidants that can oxidize and sequester many trace metals found in nature (García-Sánchez et al. 1999).
Out of the two states Cr6+ is more toxic than the other but some strong oxidants can oxidize Cr3+ to Cr6+ (Zuo and Balasubramanian 2013 ).
Indeed, strong oxidants or sulfhydryl oxidizing agents cause KATP channel closure in skeletal muscle cells [58], pancreatic β-cells [59] and cardiac cells [60].
The perfect structure of graphene is damaged when graphite is chemically oxidized by treatment with strong oxidants.
In advanced oxidation technique formation of strong oxidants plays an important role for the breakdown of pollutants into simple compounds [5].
This result can be attributed to the adding of HAuCl4 and H2PtCl6, which can serve not only as the resource of metal particles, but also as strong oxidants, which can enhance the oxidation degree of the PANI in composites [22, 23]. Figure 3 represents the UV-vis absorption spectra of PANI, PANI HAuCl4·4H2O), and PANI(H2PtCl6·6H2O) in m-cresol solution.
Advanced oxidation processes make use of strong oxidants to reduce COD/BOD levels, and to remove both organic and oxidizable inorganic components.
It is found that the targets of PFOA could be efficiently oxidized by the electro-generated strong oxidants of SO4− (from the reduction of coreactant S2O82−), thus leading to a low yield of the excited utg-C3N4 (g-C3N4*) and finally a decrease in ECL signal.
Most of the disinfectants are strong oxidants and therefore during their course of oxidation there is a tendency to occur harmful byproducts [7] which could damage healthy cells.
Water treatment is an advanced technology that oxidizes organic and toxic compounds by producing strong oxidants, OH radicals, as intermediate products.
It is clear that the increased production of signalling species (for example, nitric oxide (NO) and hydrogen peroxide (H2O2)) and strong oxidants (the hydroxyl radical (OH) and hypochlorous acid (HOCl)) act in synergy with collapse in energy metabolism to provoke cell dysfunction, which may result in organ failure and death.
