Abstract

The invention discloses a method for preparing a porous adsorption material by a magnetic control nano motor cluster gel method. The method comprises the following steps: adding an alcohol-acid organic mixture into 700-1500 DEG C smelting slag, sufficiently mixing and reacting, uniformly mixing the reaction solution and a silicon-coated magnetic micro-nano particle solution after the reaction is completed, adding the mixture into a surfactant solution, and in the presence of a magnetic field, reacting for 0.5-24 hours at the temperature of 80-180 DEG C, aging for 16-24 hours from the room temperature to 30 DEG C, collecting solids, heating and drying to obtain the porous adsorption material. The method overcomes the problems of low utilization rate of slag, single function of preparing the adsorption material and low adsorption capacity at present, realizes maximum utilization of solid waste resources, and has good environmental benefits, social benefits and economic benefits.

Description

technical field [0001] The invention discloses a method for preparing a high-quality porous adsorption material with a magnetic nanomotor and smelting slag, and belongs to the technical field of preparing the adsorption material through resource utilization of solid waste. Background technique [0002] Blast furnace slag is one of the main by-products produced in the blast furnace smelting process, and its main components are CaO, SiO 2 , MgO and Al 2 o 3 , and a small amount of FeO, MnO, Na 2 O, K 2 O and S, etc., TiO also exists in the smelting process of some special ores 2 , V 2 o 5 Wait. About 350kg of blast furnace slag is discharged into the environment for every ton of pig iron smelted. The discharge temperature is generally around 1450°C. The sensible heat contained in each ton of blast furnace slag is about 1.7GJ, and its calorific value is equivalent to 58kg of standard coal, which belongs to high Quality waste heat resource. Blast furnace slag not only c...
