Abstract

The invention belongs to the technical field of air purification materials, and particularly relates to an adsorbing material as well as a preparation method and application thereof. The preparation method of the adsorbing material comprises the steps of dissolving an oxidizing agent in water at room temperature, adding a precipitating agent into the water, reacting to obtain a mixed turbid solution, and drying the obtained product after solid-liquid separation to obtain the adsorbing material, wherein the product is firstly subjected to granulation molding and then is dried to prepare the granular adsorption material; or the product is dried and then ground to obtain the powdery adsorbing material. According to the invention, an existing preparation process of delta-MnO2 is improved, so that the process is simplified and is more beneficial to industrial production, the obtained adsorbing material has a more excellent formaldehyde purification function, when the adsorbing material is applied to equipment such as an air filter, a household or vehicle air conditioner, an air purification system or a fresh air system, a better purification effect can be achieved.

Description

technical field [0001] The invention belongs to the technical field of air purification materials, and in particular relates to an adsorption material and its preparation method and application. Background technique [0002] Commonly used formaldehyde purification methods include adsorption, plasma, chemical reaction and photocatalysis. High purification efficiency, low energy consumption, long service life and no secondary pollution are the goals pursued by various indoor air purification technologies, but the above-mentioned formaldehyde purification methods still have a certain distance from this goal under the current research level. For example, the adsorption method has the problem of service life or regeneration, which often causes secondary pollution because the filter screen is not replaced in time; the photocatalytic method has low purification efficiency, many by-products and high energy consumption; During the degradation process, it shows a high formaldehyde re...
