Embodiment 1

[0028] (1). Soak 2.5mol activated carbon fibers in 1.5mol / l NaOH aqueous solution for 2.5 hours, then filter out, wash with distilled water; then add detergent solution, ultrasonically vibrate, rinse with distilled water, and dry at room temperature for 3 hours;

[0029] (2). Put the dry active carbon fiber into 100ml mass concentration in the ethanol aqueous solution of 50%, add the Gemini surfactant aqueous solution of n=10 in 1mol above formula (I), and drop the hydrochloric acid that mass concentration is 20% Aqueous solution, reacted at room temperature for 3 hours;

[0030] (2). After the reaction, filter, wash with distilled water, and dry in a vacuum oven at 80° C. for 3 hours to obtain the air purifier material of the present invention.

Embodiment 2

[0032] This example was implemented in the same manner as Example 1, except that the Gemini surfactant in step (2) was the compound of formula (I) with n=14.

Embodiment 3

[0034] This example was implemented in the same manner as Example 1, except that the Gemini surfactant in step (2) was the compound of formula (I) with n=18.

Description

technical field [0001] The invention relates to an air purifier material, in particular to an activated carbon fiber air purifier material modified by a Gemini surfactant, a preparation method and an application thereof, belonging to the field of air purification. Background technique [0002] At present, in our country, with the improvement of people's living standards and the use of a large number of chemical raw materials for interior decoration, a large number of organic pollutants also enter the room. Health poses a serious threat. When people breathe and contact these pollutants for a long time, they can induce many symptoms such as headache, shortness of breath, skin itching, and physical fatigue. In addition, these pollutants can also induce a variety of malignant tumor diseases. one of the important factors. [0003] The removal methods of VOCs mainly include activated carbon adsorption method, plant purification method, electrostatic dust removal, photocatalysis a...
