Abstract

The invention discloses a formaldehyde adsorbent for air purification and a preparation method and application thereof. The formaldehyde adsorbent is prepared from the following raw materials in parts by mass: 56 to 62 parts of calcium carbonate, 11 to 16 parts of hydrated titanium dioxide, 32 to 37 parts of glycerol, 8 to 12 parts of evodine, 5 to 7 parts of aluminum bromide, and 87 to 92 parts of deionized water. The formaldehyde adsorbent has the advantages that the calcium carbonate is used as the main component, and is mixed with the evodine, the aluminum bromide, the hydrated titanium dioxide and the glycerol, so that the effect of adsorbing ormaldehyde is stronger; the sources of raw materials are wide, the cost is low, and the formaldehyde adsorbent is suitable for being popularized.

Description

Technical field [0001] The invention relates to the technical field of pollution treatment, in particular to a formaldehyde adsorbent for air purification and a preparation method and application thereof. Background technique [0002] Formaldehyde is an important chemical raw material and is used in large quantities in industry. Some additives (such as phenolic resin, etc.) used in various chemical building materials or products will decompose to produce free formaldehyde during use, and gradually release it into the environment, which will cause certain damage to people’s living environment, especially human health. harm. The plywood, particleboard and other man-made boards used in the decoration process, as well as the decorative wallpaper, wall covering and paint, etc., will inevitably leave formaldehyde. In recent years, with the extensive use of these decoration materials, the accompanying indoor formaldehyde pollution has always been a concern. People's long-term exposur...
