Abstract
As known to all, the quality of indoor air directly affects people’s health. Although the existence of indoor air purification products has some purification functions, there are also a variety of shortcomings. For example, activated carbon can only physically adsorb formaldehyde and cannot decompose formaldehyde, which is easy to saturate and causes secondary pollution. Based on a Japanese patent, an air purification product reacts with formaldehyde to produce N-substituted imines. Meanwhile, the products are not small molecules such as water and carbon dioxide, thus the reaction is slow and cannot meet all of the people’s needs. In this paper, a novel kind of indoor purification material is studied, which is a kind of Nanoparticle with strong oxidizing properties, showing a good function in removing formaldehyde, toluene, and other harmful gases as well as sterilization. In addition, the purification performance has been verified and compared with that of activated carbon commonly used in the market and an air purification product based on a Japanese patent, in which the main components are organic amine and amide complex. A series of experimental results show that the adsorption efficiency and capacity of the new adsorption purification material developed in this paper are much higher than those in the market. The adsorption capacity is 1.80 times that of activated carbon, and 1.13 times that of a Japanese famous brand formaldehyde removal product; The adsorption rate of the new adsorption and purification material is two times that of activated carbon, and 1.56 times that of a Japanese famous brand formaldehyde removal product. Furthermore, the new adsorption purification material has a strong inhibitory effect on common bacteria. The active substances contained in the material oxidize common bacteria in the air. The antibacterial rate of representative Escherichia coli, Staphylococcus aureus, and Klebsiella pneumonia is greater than 99%, and the antibacterial rate of Candida albicans is 96.3%. In addition, it is non-toxic, low cost, and can well meet people’s purification needs.
