Abstract

The invention discloses a PM2.5 adsorbing material, and a preparation method and application thereof, belonging to the field of PM2.5 adsorbing materials. The component of the adsorbing material is adiisopropylamine perchloric acid heterojunction with a structural formula of (((CH3)2HC-NH2-CH(CH3)2)ClO4). The preparation method comprises the following steps: dissolving diisopropylamine perchloricacid crystals into water; introducing the formed solution into a proper container, or soaking fiber cloth with the formed solution; carrying out low-temperature treatment and quenching the aqueous solution into ice; and drying the ice in a freeze dryer to obtain acicular diisopropylamine perchloric acid microcrystals, heating the acicular diisopropylamine perchloric acid microcrystals, and keeping the acicular diisopropylamine perchloric acid microcrystals in the air at room temperature for a period of time after heating is completed, thereby obtaining the diisopropylamine perchloric acid heterogeneous material. The prepared PM2.5 adsorbing material can achieve the purposes of efficiently adsorbing and removing PM2.5, and is simple in preparation method, low in cost, low in energy consumption and suitable for enterprises with serious dust pollution.

Description

technical field [0001] The invention relates to the field of PM2.5 adsorption materials, in particular to a PM2.5 adsorption material, and also relates to a preparation method and application of the PM2.5 adsorption material. Background technique [0002] With the development of the economy, the problem of environmental pollution, especially air pollution, has become more and more serious. The society has higher and higher requirements on the control of PM2.5 pollution produced in the industrial production process. PM2.5 refers to suspended particulate matter with an aerodynamic equivalent diameter less than or equal to 2.5 microns (one micron equals one millionth of a meter). The industrial production process is an important source of fine particulate matter PM2.5. The prevention and control of PM2.5 should start from the source, adopt a comprehensive management strategy, improve the existing dust removal technology and equipment, and strictly control the dust pollution ca...
