Abstract

The invention provides a formaldehyde decomposition solution prepared by nano-pollen and nano-carbon. The formaldehyde decomposition solution comprises components in percentage by weight as follows: 10% of pollen, 1% of titanium dioxide, 5% of activated carbon, 0.1% of ethyl acetate and 83.9% of distilled water. According to the formaldehyde decomposition solution prepared by nano-pollen and nano-carbon, titanium dioxide is taken as a photocatalyst to decompose formaldehyde and other indoor pollutants into CO2 and H2O; activated carbon contains a large quantity of micro pores and has a huge specific surface area, so that a photo-catalytic reaction environment is provided for titanium dioxide, the influence of the poor catalytic effect caused by titanium dioxide agglomeration is reduced, the reaction speed of photocatalytic degradation of the indoor pollutants is increased, and meanwhile, activated carbon can effectively remove odor and can absorb other pollutants in a room. The invention further provides a preparation method of the formaldehyde decomposition solution.

Description

technical field

[0001] The invention relates to a formaldehyde decomposition solution, in particular to a pollen carbon nano formaldehyde decomposition solution and a preparation method thereof. Background technique

[0002] Due to the use of artificial boards, wallpapers, foam plastics and other materials in newly decorated rooms, the indoor formaldehyde concentration is mostly higher than the national standard. Formaldehyde has a strong stimulating effect on the skin, eyes and respiratory tract, and has an anesthetic effect on the central nervous system. Formaldehyde coagulates proteins, is genotoxic to humans, and is also a mutagen. Low concentrations of formaldehyde can cause damage to the respiratory tract, and long-term exposure may damage the health of the respiratory system.

[0003] Titanium dioxide is an ideal photocatalyst, which can remove formaldehyde and degrade organic matter, but it has the problem of easy agglomeration, resulting in low catalytic efficienc...
