Background
The iron oxyhydroxide is an iron-containing inorganic compound with a molecular formula of FeOOH and a molecular weight of 88.9326. Iron oxyhydroxides can be converted to iron oxides under certain conditions. Under the irradiation of light, HO generated in the FeOOH photocatalytic reaction aqueous solution has extremely strong oxidizability, and can indiscriminately oxidize organic matters in the water body. Under the irradiation of visible light, the valence band electrons of FeOOH undergo band-to-band transition to generate photo-generated electrons (e-) and holes (h +). The O2 adsorbed on the surface of the photocatalyst captures electrons to form superoxide anions (. O2-), and then the holes oxidize hydroxide ions (OH-) and water (H2O) adsorbed on the surface of the photocatalyst into hydroxyl radicals (. HO). HO has strong oxidizing ability, can oxidize most organic matters, and finally convert the organic matters into CO2, H2O, inorganic salts and the like, thereby promoting the harmlessness of most organic pollutants. Therefore, the iron oxyhydroxide can be used for the desulfurization process in industry, has better removal effect, can replace ZnO under certain conditions, has lower cost than ZnO, and has better desulfurization effect.
In the preparation process of the iron oxyhydroxide, oxygen-containing gas is required to be used for oxidation, the existing preparation method is to directly blow the oxygen-containing gas into a solution by using an air blowing pipe, but the time for the oxygen bubbles to stay in the solution is short, so that the oxidation reaction can not be fully performed, the time consumption is long, the production efficiency is reduced, the demand for the oxygen-containing gas is large, the oxygen-containing gas is required to be continuously blown, and the cost input is increased.
