Problems solved by technology

However, the adsorption effect of formaldehyde is not very obvious. Generally, the ability of activated carbon will become weaker and weaker after one month, and the chemical pollutants are mainly removed by adsorption. Since no chemical reactions such as oxidation and decomposition occur, So the removal effect is uncertain
The above methods are generally effective for removing indoor organic pollutant gases.

Abstract

The invention discloses a nano photocatalyst. The nano photocatalyst is prepared from the following components in parts by weight: 5-15 parts of 5-8nm nano titanium dioxide, 5-10 parts of nano silicondioxide, 3-8 parts of nano AZO, 100-200 parts of deionized water and 0.5-1 part of a dispersing agent. The nano photocatalyst disclosed by the invention has the beneficial effects that an absorbent can absorb organic pollutants such as formaldehyde, ammonia, benzene and TVOC (Total Volatile Organic Compounds) effectively after indoor decoration, the use is convenient and simple, the cost is low,no rebound is caused after use, the product can not cause secondary pollution to the environment in the use process, the action time is long and the treatment is more thorough.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a nano photocatalyst. Background technique [0002] After the new house is renovated, chemical pollutants such as formaldehyde in adhesives, benzene series in paint, and ammonia released from walls will be released slowly for a long time, posing a serious threat to the health of indoor personnel. People who stay in the room for a period of time will feel dizzy, dizzy, and breathing discomfort, which directly affect the health of the indoor personnel. Therefore, it is an urgent health project to comprehensively manage the indoor environment after decoration. In the prior art, in order to remove indoor chemical pollution and improve the indoor environment, there are mainly ventilation methods, solid activated carbon adsorption, and green plant adsorption. The ability of plants to remove formaldehyde is also limited, and plants can only play an auxiliary role in the...
