Ascorbate guided conversion of hydrogen peroxide to ...

2021-3-1 · The conversion efficiency of H 2 O 2 to OH and O 2 on goethite was quantified.. Ascorbate promoted the conversion of H 2 O 2 to OH from 11% to 82%.. Ascorbate suppressed the conversion of H 2 O 2 to O 2 from 71% to 11%.. Ascorbate efficiently reduced surface Fe(III) to Fe(II), thus favoring the conversion of H 2 O 2 to OH.. Less surface Fe(III) strongly inhibited the conversion of H 2 O 2 to O 2.

Superhydrous hematite and goethite: A potential water ...

2021-7-20 · Water can be stored in nominally anhydrous minerals as substitutional hydroxyl, generating vast but commonly unrecognized H 2 O reservoirs in ostensibly dry regimes. Researchers have long known that hematite (α-Fe 2 O 3) can accommodate small concentrations of hydroxyl through the substitution of Fe 3+ by 3H +.Our study of natural hematite has demonstrated the occurrence of …

2021-7-31 · The goethite ( -FeOOH) nanorods were prepared following a procedure described by us earlier [36,37]. An aqueous dispersion of goethite nanorods was synthesized by co-precipitation of Fe3+ and Fe2+ cations at acid pH (pH ~ 4). To reach this pH value, aqueous solutions of FeCl3 (1 M, 20 mL) and of FeSO4 7H2O (2 M, 5 mL, in 1.3 M HCl) were

Effect of pH on the Formation of Goethite and Hematite …

Storage of ferrihydrite in aqueous suspensions at 24°C and pHs between 2.5 and 12 for as long as three years resulted in the formation of goethite and hematite. The proportions and crystallinity of these products varied widely with the pH. Maximum hematite was formed between pH 7 and 8, and maximum goethite at pH 4 and at pH 12. The crystallinity of both products, as indicated by X-ray powder ...

Effects of goethite on the fractions of Cu, Cd, Pb, Pand soil ...

Goethite is of great importance as it affects the migration and transformation of heavy metals and phosphorus. To further understand the effect of goethite in soil on the immobilization efficiency of heavy metals and soil biological characteristics with the application of hydroxyapatite (HAP), the fractions of Cu, Cd, Pb, and P and soil enzyme activities were determined.
