Problems solved by technology

However, the main limiting factor of such products at present is that the adsorption of functional substances to formaldehyde, benzene, toluene, and TVOC is weak and cannot be organically combined with active compounds, thus failing to achieve a good effect of removing formaldehyde. Inflicted damage has no effect

Embodiment 1

[0019] Dissolve 5 grams of potassium permanganate in an appropriate amount of pure water, add 5 grams of emulsion binder, weigh 50 grams of coconut shell activated carbon, 20 grams of tourmaline powder, and 15 grams of basic aluminum oxide, all soaked in potassium permanganate solution, stirred for 1 hour, and after being fully infiltrated, took it out and dried it under vacuum at room temperature for 5 hours to obtain gas scavenger A. Take 1 gram of gas scavenger A and put it in a place containing 0.1mg / m 3 In the air environment of formaldehyde, the environmental space is 3m 3 After 24 hours, the formaldehyde gas content in the environmental space has dropped to 0.005mg / m 3 , the environmental pollution gas content meets the national standard.

Embodiment 2

[0021] Dissolve 3 grams of potassium dichromate in an appropriate amount of pure water, add 5 grams of emulsion binder, weigh 75 grams of nano-bamboo charcoal activated carbon, 10 grams of nano-tourmaline powder, and 7 grams of magnesium hydroxide, all soaked in potassium dichromate solution, stirred for 5 hours, after being fully infiltrated, taken out at room temperature and vacuum-dried for 5 hours to obtain gas scavenger B. Take 1 gram of gas scavenger B and put it in a place containing 0.1mg / m 3 In the air environment of formaldehyde, the environmental space is 3m 3 , 24 hours later, the formaldehyde gas content in the ambient space was reduced to 0.004mg / m 3 , the environmental pollution gas content meets the national standard.

Embodiment 3

[0023] Dissolve 6 grams of potassium ammonium persulfate in an appropriate amount of pure water, add 5 grams of emulsion binder, weigh 64 grams of coconut shell activated carbon, 10 grams of tourmaline powder, and 15 grams of magnesium hydroxide, all soaked in potassium permanganate After being fully infiltrated in the solution, take it out and dry it under vacuum at room temperature for 5 hours to obtain gas scavenger C. Take 1 gram of gas scavenger C and place in a place containing 0.1mg / m 3 In the air environment of formaldehyde, the environmental space is 3m 3 , 24 hours later, the formaldehyde gas content in the environmental space was reduced to 0.003mg / m 3 , the environmental pollution gas content meets the national standard.

Abstract

The invention relates to a modified activated carbon adsorption scavenger and a preparation method. The method includes the steps of stirring nanometer active carbon and materials evenly, adding adequate water and emulsion adhesives after mixing, stirring the mixture, and after full infiltration, drying the mixture through at a room temperature and in vacuum to obtain the scavenger. Particularly, the materials comprise, by weight, 50% to 80% of nanometer active carbon, 5% to 20% of Tourmaline powder, 1% to 10% of strong oxidant, 5% to 20 % of alkaline alumina or magnesium hydroxide and 2% to 8% of emulsion adhesive. The invention belongs to the comprehensive technical fields of environmental medicine, natural products and environmental protection, environment and human health, novel materials and the like, the scavenger is mainly used for eliminating hazards of free formaldehyde, benzene, toluene and total volatile organic compound (TVOC) in the air, so that relevant air pollution in living rooms and relatively sealed space is solved, the scavenger can continuously emit far infrared rays (The wavelength is in a range from 4 mu m to 14 mu m) beneficial to human bodies, the metabolism is promoted, the hear pressure is reduced, and the like; and the scavenger has good prevention and auxiliary therapy effects on certain diseases and is good for protecting human health.

Description

【Technical field】 [0001] The invention relates to comprehensive technical fields such as environmental medicine, natural products and environmental protection, environment and human health, new materials, etc., and particularly relates to an adsorption scavenger for environmental pollutants such as air and water and a preparation method thereof. 【Background technique】 [0002] Indoor pollutant gases are mainly released from home interior decorations, paints, furniture, etc., mainly formaldehyde, benzene, toluene, TVOC, etc. According to the test report of the national authoritative department on the indoor pollutant gases formaldehyde, benzene, TVOC, etc. in residential buildings, only 7.7% of them meet the requirements of the "Code for the Control of Indoor Environmental Pollution in Civil Buildings" promulgated by the state, among which formaldehyde is the most serious. The rate of exceeding the standard was 80.8%, and the most serious exceeded the standard by 21 times. A...
