Preparation method and application method of bamboo vinegar decomposition liquid

Abstract

The invention discloses a preparation method of bamboo vinegar decomposition liquid. The preparation method comprises the following steps: firstly, preparing fresh bamboo wood, and removing impurities; secondly, soaking the bamboo wood with saline water at normal temperature, wherein the concentration of the adopted saline water is 1 to 5 percent, and the soaking time is 3 to 5 hours; thirdly, adding balsam pear leaves and mustard plant heads into the saline water in the second step; fourthly, heating and boiling the saline water in the third step, wherein the water temperature for heating and boiling is 60 to 100 DEG C, and the heating and boiling time is 3 to 5 hours; fifthly, filtering mixed liquid finished in the fourth step, and extracting the filtered liquid; sixthly, repeatedly distilling the filtered liquid for three times at the temperature of 80 to 95 DCEG C, and extracting distilled liquid; seventhly, dissolving titanium dioxide into the distilled liquid, and enabling the titanium dioxide to be saturated in the distilled liquid; and eighthly, filtering the liquid finished in the seventh step by bamboo charcoal particles to obtain colorless transparent bamboo vinegar decomposition liquid.

Description

technical field [0001] The invention relates to the preparation and application of a high-efficiency scavenger for formaldehyde, benzene, amine, acetone and other harmful chemical substances, in particular to the preparation and application method of a bamboo vinegar decomposition liquid. Background technique [0002] The most widely used scavenger technology for various harmful chemical substances such as formaldehyde, benzene, amine, and acetone on the market is photocatalyst purification technology. Photocatalyst purification technology is through photocatalytic reaction. Or oxygen can be catalyzed into photoactive groups with strong oxidizing ability, such as hydroxyl radical (OH), superoxide anion radical (O2 ), active oxygen (HO2 , H2O2), etc. Oxidative groups can strongly decompose various organic compounds and some inorganic substances with unstable chemical bonds, and can destroy the cell membrane of bacteria and the protein carrier of coagulation virus.

Problems solved by technology

[0004] However, photocatalysts have certain limitations as a scavenger for various harmful chemical substances. First, photocatalysts need to be excited by ultraviolet light to function, and ultraviolet light cannot always exist in rooms or buildings, especially some furniture, No light can be seen in places where formaldehyde is released seriously, such as processed boards, drawers, and the back of cabinets, which limits the role of photocatalysts.

Second, the photocatalyst must be made into a bonding solution with inorganic gels such as latex paint, putty powder, and white cement. A large amount of inorganic gelling substances harmful to the body are added, and chemical materials such as deodorants are also added. Therefore, while the photocatalyst removes harmful substances such as formaldehyde and benzene, the air-dried colloidal substances and titanium dioxide powder may cause indoor secondary pollution. Pollution

Third, although the photocatalyst has a strong scavenging effect on various harmful substances such as formaldehyde and benzene, it has no obvious scavenging effect on acetone

[0005] There are various defects in the photocatalyst in the prior art, and it is difficult to adapt to the development trend and actual needs of today's harmful chemical substance scavengers. Preparation and application method of bamboo vinegar decomposition liquid
