This result probably indicates the existence of Fe(OH)3o as well as Fe(OH)2+ in the normal pH range of seawater. The solubility and dissolution rate constants were one order of magnitude and one-third, respectively, lower than those of amorphous hydrous ferric oxide determined in a previous...
From the thermodynamics and kinetics views, the formation of Fe(OH)3/FeOOH and Ca6(Al(OH)6)2(SO4)3·26H2O (Al-AFt) was favored instead of Ca6(Fe(OH)6)2(SO4)3·26H2O (Fe-AFt) as the solubility product (log(Ksp)) of Fe-AFt was −44.0 higher than that of Al-AFt (−44....
The temperature dependence of the solubility of proton defects in SrTiO3 single crystals was investigated by IR spectroscopy. Based on the integrated absorption of the OH stretching vibration bands, the enthalpies of the dissolution reaction were determined for undoped and Fe-doped SrTiO3. In ...

Solubility of andradite, Ca3Fe2Si3O12, in a 10 mol% NaCl solution at 800 °C and 10 kbar: Implications for the metasomatic origin of grandite garnet in cal... The results permit a test of a model of CaSiO3 dissolution in NaCl solutions to three dominant aqueous species: CaCl+, OH,...
Despite the higher sensitivity of melanoma towards ferroptosis and photodynamic therapy (PDT), the lack of efficient ferroptosis inducers and the poor solubility of photosensitizers restrict their synergistic strategies. With unique advantages, carbon do
These polymers can effectively improve the water solubility and stability of nanomaterials, but the size of nanoparticles is also significantly increased, relevant studies were shown below. Hong et al. [30] coated SPIONs with dextran to stabilize monocrystalline structures to form a stable magnetic ...
The model has been used to determine the solubility of Fe(III) in seawater as a function of pH. The results are in good agreement with the measurements of Byrne and Kester and Kuma et al. When the formation of Fe organic complexes is considered, the solubility of Fe(III) in seawater ...
