Sentence examples for by reductive dissolution of from inspiring English sources

These measurements indicate that high concentrations of metals are potentially available for release by reductive dissolution of the ferric-bearing secondary minerals.

In the proposed new reaction architecture the cycle can be partially carried out in the aqueous phase by reductive dissolution of cerium(IV) oxides to cerium III) chlorides in an azeotropic hydrochloric acid solution.

Nitrate reduction was likely due to microbial degradation of accumulated organic matter coupled with successive consumption of O2 and NO3− in the macropore water followed by reductive dissolution of Fe and Mn from minerals along the macropores.

When Eh decreased, Group I metals (Ba, Co, Cr, Ni, and V) were constantly released (< 50% as colloids) closely correlated with the release of Fe and Mn by reductive dissolution of (oxyhydr oxides.

However, because phosphate associates strongly with Fe(III) oxides [e.g. [14]], dissolved phosphate can also be released to solution by reductive dissolution of Fe oxides [e.g. [48, 49, 56 58]].

Ayers et al. [12] examined the causes of salinization and arsenic contamination of groundwater resources in Polder 32 in southwest Bangladesh and found that salts in the shallow aquifer groundwater were derived from connate water, whereas sedimentary As was mobilized by reductive dissolution of ferric oxyhydroxides.

The anoxic zone had approximately 0.07 μM As V) but also had As III) concentrations of 0.07 0.14 μM, suggesting that release of As bound to sediment grains occurred by desorption by phosphate, reductive dissolution of Fe oxides, and reduction of As V) to As III), which adsorbs only weakly to the Fe-oxide-depleted material in the coatings.

Arsenic mobility in the Guandu wetland is primarily caused by the reductive dissolution of As-containing Fe-oxyhydroxides and the redox cycling of sulfate/sulfide, accompanied by the respiration of OM.

The high aqueous As content in the boundary of the transitional and reducing zones was caused by the reductive dissolution of highly dissolved Fe compounds through the microbial respiration of organic matter (OM).

The presence of As in groundwater seems to be caused by reductive dissolution linked to the presence of dissolved organic matter.

The Chao reagent (0.25 M hydroxylamine hydrochloride in 0.25 M HCl) removes amorphous Fe and Mn oxides and oxyhydroxides (present as coatings on grains and amorphous minerals) by reductive dissolution and is a measure of reducible Fe and Mn in sediments.
