What is the effect of activated carbon in absorbing formaldehyde? Which type of activated carbon is
We all know that formaldehyde is very harmful to our human body, so we must absorb formaldehyde before moving into a new house. There are many ways to adsorb activated carbon, this is one of the methods of activated carbon adsorption, but activated carbon is actually divided into many types of activated carbon, and which activated carbon has a better absorption effect?
Activated carbon is mainly used to absorb harmful gases such as formaldehyde, filter out insoluble matter, and absorb some soluble matter. Activated carbon is mainly made of charcoal, various shells and coal as raw materials, and is processed and manufactured through a series of processes such as crushing, screening, catalyst activation, rinsing, drying and screening by physical and chemical methods. It has strong physical and chemical adsorption, and can adsorb certain organic compounds to achieve removal effect.
Activated carbon can absorb formaldehyde, ammonia, benzene, xylene, radon and other indoor harmful gas molecules in the air. It is used in living rooms, furniture closets, bookcases, shoe cabinets, shoes, refrigerators, bathrooms, floors, fish tanks, cars, air conditioners, computers, hotels and entertainment venues. It has a good effect and can effectively absorb harmful gases such as formaldehyde, filter out insoluble matter, and absorb some soluble matter. Therefore, they are used as household formaldehyde removal and indoor air purification together with gas catalysts and other chemical treatment methods.
Which type of activated carbon is effective in removing formaldehyde?
Activated carbon can be divided into wood activated carbon, shell activated carbon, mineral raw material activated carbon, synthetic resin activated carbon, regenerated activated carbon, etc. We usually use the following types of activated carbon.
1.Mineral raw material activated carbon
Mineral raw material activated carbon is mainly composed of active ore, which is mainly derived from mining areas. The raw materials are screened, and sea foam and attapulgite are added to greatly improve the adsorption performance of activated carbon.
2. Coconut Shell Charcoal
Coconut shell activated carbon is mainly made of coconut shells from Hainan and Southeast Asia, which are then screened, refined by steam carbonization, and then made through a series of processes such as impurity removal, activation, and screening. Coconut shell activated carbon is black granular, with a well-developed pore structure and adsorption capacity, high strength, good chemical stability, and long service life. It is widely used in the deep purification and refining of precious metals in pure water, industrial water, drinking water, food and beverage, petroleum and electricity, and has the functions of decolorization and deodorization, adsorption and turbidity removal, and the effect of using zeolite and molecular sieve is better.
3. Fruit shell charcoal
Fruit shell carbon is mainly made of sawdust and fruit shells, and then carbonized, activated and processed. Fruit shell carbon has large specific surface area, high strength, developed pore structure and strong adsorption performance. It can effectively adsorb organic pollution and organic solvents in water and is suitable for purification industries such as pharmaceuticals, petrochemicals, sugar making and beverages.
4. Charcoal
Wood activated carbon is made of wood as raw material and is in powder form. It is processed through high-temperature carbonization and activation. It has a large specific surface area, high activity, developed micropores, strong decolorization ability, and large pore structure. It can effectively absorb colored substances and impurities in liquids.
