Sentence examples for oxidative dissolution from inspiring English sources

Iron oxidizers can promote oxidative dissolution of arsenic minerals through direct or indirect mechanisms, which results in the production of toxic arsenious (H3AsO3) and arsenic acids (H3AsO4) [ 7].

To avoid oxidative dissolution of the semiconducting oxide during electrodeposition (by potential cycling) of a thin organic film (oligoaniline, as demonstrated using Raman spectroscopy), the over-coating step has been done in the external methanol solution.

The most common microbial arsenic mobilization processes involve oxidative dissolution of minerals through oxidation of iron, sulfur, or arsenic [ 6].

In the context of Fe0 remediation, an initial phase of increased contaminant removal is related to several processes including (1) Fe0 oxidative dissolution and (ii) precipitation of iron oxides upon local sursaturation.

The rate controlling step for sphalerite dissolution in Fe-free acid solution was found to be the oxidation of sphalerite, while in Fe-containing solution, the sphalerite oxidative dissolution is controlled by diffusion of Fe(III) within the passive layer and charge transfer process at the interface between mineral electrode and electrolyte.

In Ox IV (0.3 VSCE < E) oxidative dissolution of CrIII becomes important, resulting in a predominantly iron oxide film on the alloy.

One possible reaction pathway for the oxidative dissolution of arsenopyrite is similar to a proposed mechanism for pyrite oxidation,[25, 26] whereby the sulfur at the mineral surface forms a series of sulfoxy anions culminating in thiosulfate, which is then released to solution: 2FeAsS s) +14Fe3+(aq) + 9H2O → 16Fe 2+ (aq) + S2 O32- (aq) + 2 H3 AsO3(aq) + 12H+(aq)     (3).

The DH effect was attributed to the oxidative dissolution process of Ni following the reduction of Ni in the oxide by H2, indicating the selective dissolution of Ni in the oxide plays an important role in the corrosion of Ni-base alloys in high temperature hydrogenated water.

In the present study, a novel electro-oxidative dissolution process of V2O3 to VO43− is achieved by the in-situ generated reactive oxygen species on the N-doped carbon felt cathode in alkaline media.

Together, the EIS data and Raman spectroscopy results strongly supported the proposed mechanisms for the oxidative sphalerite dissolution through the anodic potential range.

The predominant reaction on the electrode surface at 400 mV vs. Ag/AgCl is oxidative sphalerite dissolution, in which zinc ions and elemental sulfur layer, as a passive layer, form through the electrochemical reaction.
