Abstract

The invention discloses an iron-based porous adsorption material and its preparation and application in wastewater treatment. The iron-based porous adsorption material is mainly composed of Fe 2 o 3 and carbon black as raw materials, the content of elemental iron is 50%‑70%, Fe 2+ with Fe 3+ The content of carbon is 22-49%, and the content of elemental carbon is 1-8%. The iron-based porous adsorption material is prepared by powder metallurgy. During preparation, Fe is first weighed according to the molar ratio 2 o 3 With carbon black, then add pore forming agent CaCl 2 , add it to a ball mill jar for grinding; add absolute ethanol to the ground raw material, pour it into an electro-hydraulic sample maker for sample preparation, and sinter it in a vacuum atmosphere furnace; the invention is easy to use and simple to operate. Pollutants in the water can be adsorbed after entering the water body, and can be salvaged manually after the adsorption is completed. This method of treating wastewater is easy to operate, greatly reduces labor intensity and treatment and recovery costs, is simple, easy to operate, and has a wide range of applications.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to an iron-based porous adsorption material, its preparation method and its application in wastewater treatment. Background technique [0002] Porous metal material is a new type of engineering material with excellent physical properties and good mechanical properties developed in the late 1980s. Porous metal material has low density, high rigidity, large specific surface area, good noise reduction effect, and electromagnetic shielding performance. High and excellent physical properties are widely used in functional materials such as catalysts and catalyst carriers, high-temperature liquid filters, heat exchangers, etc., and can also be used as structural materials in aviation, construction and other fields. [0003] At present, wastewater is mainly treated by physical, chemical or biological methods to purify wastewater and reduce pollution, so as to achieve the purpose of recycl...
