Abstract

The invention discloses a negative oxygen ion photocatalyst decomposition liquid for formaldehyde removal and a preparation method thereof. The liquid is prepared from 14 parts of a formaldehyde trapping agent, 3-5 parts of a nano photocatalyst, 3-5 parts of nano silver ions, 4-6 parts of negative ion powder, 6-10 parts of cellulose, 3-5 parts of ethanol, 0.3-0.7 part of essence and 75.3-80.5 parts of deionized water. The negative oxygen ion photocatalyst decomposition liquid for formaldehyde removal and the preparation method thereof have an excellent catalytic degradation function, can release negative oxygen ions for a long time and can thoroughly kill bacteria and microorganisms since the formaldehyde trapping agent, high-activity nano Ti02 and Ag+ with a high-efficiency sterilizationfunction are added. Harmful gas such as formaldehyde, benzene, VOC and the like brought by the bacteria, the microorganisms and decoration can be thoroughly caught and decomposed, spatial structures of organic molecules are changed and convert into tasteless and harmless molecules, negative oxygen ions are released, sterilization and disinfection are carried out, and therefore indoor air is thoroughly and effectively purified.

Description

technical field [0001] The invention belongs to the field of air purification, and in particular relates to a formaldehyde-removing decomposition liquid by a negative oxygen ion photocatalyst and a preparation method thereof. Background technique [0002] Air is one of the important external environments that human beings depend on for survival, so indoor air pollution comes from organic pollutants released from interior decoration and furniture, such as formaldehyde, benzene, toluene, diphenyl, VOC and other harmful gases. If humans live in such a polluted environment, it can cause eye, nose, throat and respiratory tract irritation, headache, dizziness, nausea, chest tightness, lack of energy and other symptoms, and these symptoms can be relieved or disappeared when they leave this environment. The World Health Organization (WHO) research shows that long-term exposure to harmful gases such as formaldehyde, benzene, toluene, diphenyl, VOC, etc., may cause malignant diseases ...
