Akaganeite (β-FeOOH) has been prepared by the hydrolysis of FeCl3 solutions. The effects microwave heating, pH solution, and addition manganese with different valence states have studied for optimization its synthesis. nucleation growth akaganeite crystallites are accelerated heating. A low favors crystallization akaganeite, a high hematite. Addition appears to impede at but improves it pH. anion exchange Cl-akaganeite F-, Br-, OH- some properties anion-exchanged akaganeites investigated....
The distribution of Fe resulting from the autocatalytic interaction aqueous Fe(II) with hematite (α-Fe2O3) (001) surface was directly mapped in three dimensions (3D) for first time, using isotopic labeling and atom probe tomography (APT). Micrometer-sized platelets were reacted enriched 57Fe prepared APT conventional focused ion beam lift-out techniques. Mass spectrum analyses show that specific Fe-ionic species (i.e., Fe2+ FeO+) accurately reproduce ratios within natural abundance bulk,...
The aim of this study was to investigate the effects inorganic cations (Na+, Ca2+, and Al3+) with different valences concentrations on stability Na-montmorillonite (Na-MMT) suspension. studied by turbidity zeta potential measurements adsorption thermodynamics. results showed that Na-MMT particles coagulated at pH 3–4.8, which much inhibited higher concentration valence. This caused reduction electrostatic repulsion. Adsorption Ca2+ surface fits Freundlich curve model well. Furthermore,...
