Embodiment 1

[0023] A kind of peculiar smell remover, is prepared from the following raw materials by weight:

[0024]

[0025]

[0026] Specifically, the anionic surfactant is sodium alkylsulfonate, and the dispersant is polyacrylic acid sodium salt.

[0027] Concrete preparation method comprises the following steps:

[0028] S1: Synthesis of Nano Titanium Dioxide

[0029] Take 35 parts by weight of absolute ethanol at room temperature, add 10 parts of tetra-n-butyl titanate and mix and stir. After 0.5 hours, slowly add glacial acetic acid dropwise to the mixed solution, and vigorously stir for 0.5 hours to obtain a light yellow transparent solution. Slowly add 8 parts by weight of distilled water dropwise, and continue stirring for 1 hour to obtain a light yellow transparent sol. After aging at room temperature for 24 hours, vacuum-dry. The drying temperature is 80 degrees Celsius, and the drying time is 24 hours. After grinding, a white precursor is obtained. , the precursor is ...

Abstract

The invention belongs to the technical field of odor removal, and particularly relates to a peculiar smell scavenger and a preparation method thereof. The peculiar smell scavenger is prepared from, byweight, 1-2% of chlorophyll copper sensitized nano titanium dioxide, 94-97.8% of anhydrous ethanol, 0.2-2% of an anionic surfactant and 1-2% of a dispersing agent, and the preparation method of the peculiar smell scavenger is simple in process. The peculiar smell scavenger provided by the invention comprises copper chlorophyllin sensitized nano titanium dioxide and anhydrous ethanol as the main components, is environmentally friendly and non-toxic, and the copper chlorophyllin sensitized nano titanium dioxide in the anhydrous ethanol is relatively simple in component, stable in property, goodin dispersion effect, long in storage time and convenient to transport and store compared with being in a water solvent, and the chlorophyll copper sensitized nano titanium dioxide has a good naturalvisible light absorption effect, does not need to be irradiated by ultraviolet rays, and has a good use effect under the natural visible light irradiation condition.

Description

technical field [0001] The invention belongs to the technical field of odor elimination, and in particular relates to an odor elimination agent and a preparation method thereof. Background technique [0002] With the development of the economic level, people's living standards are improving day by day, and people's requirements for keeping the environment clean and the air fresh are getting higher and higher. However, with the acceleration of urbanization, environmental pollution is becoming more and more serious, harmful substances and odors that people are exposed to (oxygen-containing organic substances such as aldehydes, phenols, alcohols; sulfur compounds such as hydrogen sulfide and sulfur dioxide; nitrogen compounds such as ammonia and amines, etc.) ) is increasing, long-term exposure to these substances will cause great harm to people's nervous system, respiratory system, endocrine system, digestive system, etc., and have a great impact on health. How to efficiently...
