Adsorptive deodorizing materials, preparation methods, and air purification devices

An adsorptive deodorizing material, comprising:

• in parts by weight, 230 to 240 parts of activated carbon powder, 45 to 55 parts of deionized water, 15 to 25 parts of a manganese compound, 10 to 15 parts of a soluble copper salt, 10 to 15 parts of phosphoric acid, and 8 to 10 parts of a soluble nickel salt;
• wherein the phosphoric acid is industrial phosphoric acid with a purity of 85%;
• the activated carbon powder has a mesh size of 240-400 mesh;
• the adsorptive deodorizing material has a specific surface area of 1000-1500 m2/g;
• and
• the adsorptive deodorizing material is prepared by a process including:
• stirring and mixing the deionized water, the manganese compound, the soluble copper salt, the phosphoric acid, and the soluble nickel salt to obtain a chemical agent;
• spraying 40%-60% of a total mass of the chemical agent onto the activated carbon powder, stirring and mixing, placing the activated carbon powder mixed with the 40%-60% of the total mass of the chemical agent into a mold for molding, and performing a sintering step after molding to obtain a semi-finished adsorptive deodorizing material;
• soaking the semi-finished adsorptive deodorizing material in a remaining portion of the chemical agent;
• and
• drying the semi-finished adsorptive deodorizing material after soaking to obtain the adsorptive deodorizing material.
