Abstract

The invention provides a method for preparing an activated carbon material, the activated carbon material prepared by the method and application of the activated carbon material in a filter. The method for preparing the activated carbon material comprises the following steps: (1) adding a quaternary ammonium salt monomer into deionized water, and uniformly stirring to enable the molar concentration of the quaternary ammonium salt monomer to be 0.6 mol / L-1. 4mol / L so as to obtain a solution A; (2) adding an initiator into the solution A to obtain a solution B; (3) adding granular activated carbon into the solution B, and uniformly stirring to obtain a mixture C; (4) introducing nitrogen into the mixture C, bubbling for 10 minutes, sealing, and carrying out oxidation-reduction grafting reaction in a constant-temperature water bath; and (5) washing the product after the oxidation-reduction grafting reaction with acetone, extracting for 24 hours, and drying to obtain the activated carbon material. The activated carbon material prepared by the method has relatively strong adsorption performance and also has good antibacterial and anti-corrosion performance.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a method for preparing an activated carbon material, the activated carbon material prepared by the method and the use of the activated carbon material in filters. Background technique [0002] With the continuous development of my country's economy, automobiles have become an indispensable means of transportation for people's daily life. As the number of private cars in cities increases year by year, the air pollution on the road is becoming more and more serious. However, the space inside the car is small and the air circulation is poor, which is not conducive to the diffusion of pollutants, and is easy to breed bacteria, which has a great impact on the health of car owners. hazards. How to improve the air quality in the car has become a topic of close concern to the majority of car owners, and the air conditioner filter with antibacterial function will be an effective mean...
