Abstract
The invention discloses a method for preparing one-dimensional nanostructures of titanium dioxide with melting slag of titanium containing electric furnace, belonging to the preparing field of metal oxide material. The invention uses melting slag of titanium containing electric furnace having wide variety of sources, sequentially comprising the following steps: crushing the melting slag of titanium containing electric furnace and uniformly stirring with sodium hydroxide solution, putting into a special reaction kettle for water heating, heating to a specified temperature and keeping the temperature for a time period; through filtering, drying, ultrasound, acidolysis, centrifuging and calcining, preparing the one-dimensional nanostructures of titanium dioxide with melting slag of titanium containing electric furnace; the problem that the melting slag of titanium containing electric furnace is more and more is effectively solved; the titanium extraction process is simplified, and the energy consumption is reduced. The one-dimensional nanostructures of titanium dioxide prepared by this method has obvious photocatalytic effect, which can be used for degrading organic waste water, so as to realize the waste control by using waste; a new process for comprehensive utilization of melting slag of titanium containing electric furnace is provided.
