Embodiment 1

[0019] The specific implementation steps are as follows:

[0020] (1) Take 2.5g of illite and 2.5g of glucose and disperse in 50mL water for 30min to prepare a mixed suspension;

[0021] (2) Transfer the mixed suspension obtained in step (1) into an autoclave, and conduct a hydrothermal reaction at 160° C. for 24 hours;

[0022] (3) washing and filtering the reaction product obtained in step (2) with ethanol and water, and drying at 60° C. for 12 hours;

[0023] (4) Grinding the dried product obtained in step (3) until 97% passes through a 200-mesh sieve to obtain illite-loaded nano-carbon composite adsorption material.

[0024] The SEM and TG figures of the illite-loaded nano-carbon composite adsorption material prepared in Example 1 are shown in the appendix figure 2 and 3 . Depend on figure 2 It can be seen that the illite sheet surface is evenly loaded with nano-carbon particles, and its average particle size is 30-50nm; image 3 It can be seen that the loading amo...

Embodiment 2

[0026] The steps are the same as those in Example 1, except that the amount of sucrose added in step (1) is 5.0 g, dispersed with 60 mL of water; the reaction temperature in step (2) is 180° C., and the reaction time is 20 h;

Embodiment 3

[0028] The steps are the same as those in Example 1, except that the amount of starch added in step (1) is 7.5 g, dispersed with 70 mL of water; the reaction temperature in step (2) is 200 ° C, and the reaction time is 16 h;

Abstract

The invention relates to an illite loaded nanocarbon compound adsorbing material and a preparation method thereof and belongs to the field of non-metallic mineral material and environmental engineering. According to the invention, illite is taken as a carrier, soluble saccharide is taken as a carbon source and nanocarbon grains are uniformly loaded on the surface of an illite layer, so that the nanocarbon compound adsorbing material taking illite as the carrier is obtained. In the prepared illite loaded nanocarbon compound adsorbing material, the average grain diameter of the nanocarbon grains is 30-50nm, the nanocarbon grains are uniformly and compactly distributed on the surface of the illite layer and the load volume is 30%-70% of the mass of the compound material. According to the material, the illite carrier effect is utilized to increase the adsorbing capturing performance of the compound material to the pollutant and the dispersity of the adsorbent; the obtained raw materials are easily acquired and are low in cost; the preparation technique is simple and the reaction condition is mild; the illite loaded nanocarbon compound adsorbing material has higher application value in the field of wastewater treatment.

Description

technical field [0001] The invention relates to an illite-loaded nano-carbon composite adsorption material and a preparation method thereof, belonging to the fields of non-metallic mineral materials and environmental engineering. Background technique [0002] In today's society, the problem of wastewater pollution is becoming more and more serious. In some areas, wastewater pollution has seriously damaged the ecological balance and directly threatened the survival of human beings. Traditional polluted wastewater treatment technologies include chemical precipitation, ion exchange, membrane osmosis and co-precipitation. However, these methods generally have problems such as high operating costs, low processing efficiency, and difficulty in repeated use, and cannot be applied industrially. The adsorption method has the advantages of simple operation process, large processing capacity, and reusability, and is an ideal wastewater treatment technology. Common adsorbent material...
