METHOD FOR MANUFACTURING IRON OXIDE NANOTUBES, IRON OXIDE NANOTUBES MANUFACTURED THEREBY, METHOD FOR MANUFACTURING MAGNETIC IRON POWDER, AND DEVICE FOR REMOVING AND RECOVERING PHOSPHATE USING SAME

摘要

The present invention relates to a method for manufacturing iron oxide nanotubes and iron oxide nanotubes manufactured thereby and, more particularly, to a method for easily and conveniently manufacturing iron oxide nanotubes, which have excellent capability to adsorb and desorb phosphate due to the high specific surface area thereof, and iron oxide nanotubes manufactured thereby, which can easily remove and recover phosphorous. The present invention is advantageous in that iron oxide nanotubes can be acquired, which have cylindrical tubes evenly formed on the surface thereof in nano-sized structures, which have a large specific surface area, thereby having excellent capability to adsorb and desorb phosphate, and which can be reused, thereby being usefully applicable even during actual processes. The present invention also relates to a method for manufacturing magnetic iron powder and a device for removing and recovering phosphate using the same and, more particularly, to a method for manufacturing magnetic iron powder conveniently and easily, which has excellent capability to adsorb and desorb phosphate, and a device for removing and recovering phosphate, which has been improved to further increase the efficiency of magnetic iron powder. According to the present invention, magnetic iron power can be simply manufactured, which not only has excellent capability to adsorb and desorb phosphate, but also can be reused, thereby being usefully applicable even during actual processes. There is also another advantage in that, when the magnetic iron powder is used for the device for removing and recovering phosphate according to the present invention, high-purity phosphate can be secured, and the recovered magnetic iron powder can also be used repeatedly.
