Abstract

The invention provides a preparation method of an activated carbon material, the activated carbon material prepared by adopting 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 phosphonium salt monomer into deionized water, and performing uniform stirring to enablethe molar concentration of the quaternary phosphonium salt monomer to be 0.5 mol / L-1. 0mol / 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 performing uniform stirring to obtain a mixture C; (4) introducing nitrogen into the mixture C, performing 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, performing extractingfor 24 hours, and performing drying to obtain the activated carbon material. The activated carbon material prepared by adopting the method has the relatively strong adsorption performance and also hasthe good antibacterial and anti-corrosion performance.

Description

technical field [0001] The invention belongs to the field of materials, and specifically 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 a filter. Background technique [0002] With the continuous development of my country's economy, automobiles have become an indispensable means of transportation in people's daily life. With the increasing number of private cars in the city year by year, the air pollution on the road is becoming more and more serious. The small space inside the car and poor air circulation are not conducive to the diffusion of pollutants, and it is easy to breed bacteria, which brings great harm to the health of car owners. hazard. How to improve the air quality in the car has become a topic that the majority of car owners pay close attention to. The air conditioner filter with antibacterial function will be an effective means to solve this ...
