摘要: Oxidation of As(Ⅲ) in water by iron(Ⅱ)-catalyzed potassium persulfate as well as the influence of various pH and initial concentration of Fe(Ⅱ) was investigated. The potential radicals and possible oxidation mechanism were also studied.关键词:...
200°C, an almost complete reduction proceeds in a solid state reaction forming Fe(II). It is accompanied by the release of HCl and, to a minor degree, carbon containing species. A multi-phase product with at least two chloroferrate species, coke, and C,H,N-containing polymers is formed...
Among these electronic properties, oxidation state is considered as a typical parameter to correlate with the catalytic activity. However, specific relationship between oxidation state and catalytic activity remains controversial in whether higher or lower oxidation states benefit the enhancement of catalytic ...
This enables the characterization of soot nanoparticles through quantitative analysis and correlates the nanostructures with macroproperties of soot. As the maturation process of soot is the same50,51,52, the maturity level and corresponding oxidation model of soot from different conditions can be ...
A magnetic route has been applied for measurement of the average oxidation state (AOS) of mixed-valent manganese in manganese oxide octahedral molecular sieves (OMS). The method gives AOS measurement results in good agreement with titration methods. A maximum analysis deviation error of +/-7% is...
Myocardial glucose transport, glycolysis, andglucose oxidationare all dependent directly or indirectly on insulin and so will all be reduced in the insulin-deficient diabetic state (158). In addition, high levels of circulating fatty acids in the diabetic state contribute to the overall low rates ...
depending on the pH and the oxidation state of Mn (Mn(III) versus Mn(IV)). As a result, whileMn2+can adsorb on both edge and vacancy sites (Wang et al., 2019), As(III) and As(V) oxyanions adsorb only on the edge sites (Tournassat et al., 2002). Furthermore, Mn(IV) is ...
surface and morphological investigation of the electrode/electrolyte properties in an all-solid-state battery using a li 2 s-p 2 s 5 solid electrolyte All-solid-state lithium-ion batteries represent a promising battery technology thanks to the replacement of the volatile and flammable state-of-t...

(XPS). Upon oxygen adsorption, two-coordinated ferrous sites at the steps of FeO become three-coordinated, as is the case for Fe atoms inside the FeO nanostructures. Thus, FeO should remain the Fe2+state with oxygen attached to the step edges. Accordingly, in the XPS spectra (Supplementary ...
