Problems solved by technology

However, the unstable O atoms produced during the disinfection process are extremely active and easily react with other substances in the air. When O3 is produced, nitrogen oxides and a small amount of by-products with peculiar smells and sulfides are also produced, which are harmful to human health. healthy

Embodiment Construction

[0021] Below in conjunction with embodiment the present invention is described in further detail.

[0022] 1) Weigh each component according to the proportion.

[0023] 2) Prepare component A:

[0024] ①Zeolite loaded TiO 2 Preparation: Weigh nano-TiO 2 5g, Degussa Nano P25 was used in this example, dissolved in 500ml aqueous solution containing 0.025g sodium dodecylbenzenesulfonate, ultrasonically stirred at 300rpm for 1 hour, impregnated into 1000g of natural zeolite, stirred for 1 hour , dried at 105°C for 2 hours, calcined at 300°C for 2 hours, and crushed into 80-mesh powder to obtain zeolite-supported TiO 2 .

[0025] ② Activated carbon loaded TiO 2 Preparation: Weigh nano-TiO 2 2.5g, this embodiment uses Degussa Nano P25, dissolved in 500ml aqueous solution containing 0.025g of sodium dodecylbenzenesulfonate, stirred ultrasonically at 300r / min for 1 hour, impregnated it into 500g of activated carbon, stirred for 1 hours, dried at 105°C for 2 hours, calcined at 30...

Abstract

The invention relates to an adsorbent and a preparation method thereof. The adsorbent is characterized by comprising 40-60 weight parts of a component A, 1-10 weight parts of a component B, 30-60 weight parts of a component C and 1-10 weight parts of a component D, wherein the component A comprises nanometer TiO2 and an adsorbing material; the adsorbing material is selected from natural zeolite and / or activated carbon; the amount of the TiO2 accounts for 0.2-2 percent of the total weight of the component A; the component B is selected from anhydrous magnesium sulfate and / or anhydrous calcium chloride; the component C is selected from calcium oxide and / or calcium hydroxide; and the component D is selected from sodium bicarbonate and / or ammonium bicarbonate. According to the adsorbent provided by the invention, the odor in the workplace can be initiatively adsorbed and can be subjected to catalytic oxidation under the ultraviolet light effect, so that harmful odor molecules adsorbed to the surface of the adsorbent can be degraded or decomposed; and moreover, the ambient humidity can be balanced, the adsorbent is anti-mildew, long in service life and large in superficial area, and the adsorption capacity is improved.

Description

technical field [0001] The invention relates to an adsorption material, in particular to a deodorant and a preparation method. Background technique [0002] Low-temperature ultraviolet ozone disinfection is to sterilize utensils in all directions through the direct radiation of ultraviolet rays and the dispersibility of ozone. Its advantages can sterilize a variety of utensils at room temperature. However, the unstable O atoms produced during the disinfection process are extremely active and easily react with other substances in the air. When O3 is produced, nitrogen oxides and a small amount of by-products with peculiar smells and sulfides are also produced, which are harmful to human health. healthy. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an adsorbent capable of degrading or decomposing harmful substances under the action of ultraviolet light in view of the current state of the art. [0004] Another ...
