Embodiment 1

[0020] (1) Soak the sycamore seed fluff in 50mL, 0.1mol / L hydrochloric acid solution for 12-24 hours, filter and wash with distilled water until the pH value of the filtrate is neutral, and dry it in a drying oven at 60-80°C for 12-24 hours. Obtain the preprocessed biological template;

[0021] (2) Put the pretreated biological template in step (1) into 20mL of a mixed solution of aluminum chloride hexahydrate and magnesium chloride hexahydrate with a molar mass ratio of 1:1, soak at room temperature for 24-48 hours, take out and filter , dried in a drying oven at 60-80°C for 12-24 hours to form bio-AlCl 3 -MgCl 2 ;

[0022] (3) Bio-AlCl 3 -MgCl 2 Put it into the muffle furnace and carry out two-step roasting under oxygen atmosphere. The first step is to keep warm at 400-600°C for 60 minutes, and the second step is to keep warm at 800-1000°C for 120 minutes. The heating rate of the muffle furnace is 0.4-3°C / min, and then naturally cooled to room temperature to form an Al...

Abstract

The invention discloses a preparation method of an Al-Mg oxide defluorination material based on a biological template, and belongs to the technical field of environmental functional material preparation. In the preparation process of the material, tree seed hair of oriental plane tree with tubular structure characteristics is used as a biological template to obtain the Al-Mg oxide defluorination material based on the biological template. The method uses the natural waste tree seed hair of the oriental plane tree as the biological template, by combination of a biological material with a chemical material, the Al-Mg oxide defluorination material with a better fluoride removal effect can be obtained without addition of a precipitator in the preparation process, and the preparation method hasthe advantages of being simple and green, full in utilization of natural resources, energy-saving and low-consumption.

Description

technical field [0001] The invention discloses a preparation method of an Al-Mg oxide defluorination material based on a biological template, and belongs to the technical field of preparation of environmental functional materials. Background technique [0002] The microstructure is crucial to the performance of materials. Plants and organisms in nature have formed a large number of unique microstructures through long-term evolution and natural selection. Biological templates existing in nature provide new directions for high-performance and multifunctional materials. So far, biological materials such as spherical yeast, viruses, cotton cellulose, and poplar and catkins have been used as biological templates to prepare a series of functional materials. The organic combination of biological materials and chemical materials is one of the effective ways to use natural resources to serve human beings. [0003] With the development of human civilization, water pollution has bec...
