1. What is activated carbon
Activated carbon is also known as activated carbon black. Black powder or granular amorphous carbon. The main components of activated carbon include oxygen, hydrogen and other elements in addition to carbon. From the structural point of view, the arrangement of microcrystalline carbon is irregular, and there are pores between the crosslinks. When activated, carbon structure defects will be generated, so it is a porous carbon with low packing density and large specific surface area. Activated carbon is odorless, tasteless, without sand particles, insoluble in any solvent, has selective adsorption capacity for various gases, and has high capacity adsorption capacity for organic pigments and nitrogenous alkalis. The total surface area per gram can reach 500-1000 square meters. The relative density is about 1.9-2.1, and the apparent relative density is about 0.08-0.45.
2. The role of activated carbon
Activated carbon is a very fine carbon particle with a large surface area, and within the carbon particle there are even smaller pores - capillaries. This kind of capillary has a strong adsorption capacity, and due to the large surface area of the carbon particles, it can fully contact with the gas (impurity). When these gases (impurities) meet the capillary, they will be adsorbed and play the role of purification.
The role of activated carbon is mainly to absorb harmful gases, filter out insoluble matter, and adsorb some soluble matter. The main components of activated carbon are charcoal, various fruit shells and high-quality coal as raw materials, and the raw materials are crushed and screened by physical and chemical methods. , catalyst activation, rinsing, drying and screening processes. For the first time in the world, the function of activated carbon was used to make gas masks. Later, the function of activated carbon was mainly used for the deodorization of activated carbon in waterworks.
Everyone is familiar with activated carbon. The most commonly used is to use it to absorb harmful substances such as formaldehyde and xylene in newly renovated houses. It can purify the air and benefit the physical and mental health of residents. The following editor also summarizes some other daily uses of activated carbon, let's take a look together.
Activated carbon can remove residual chlorine, colloids, organic matter, heavy metals (such as mercury, silver, cadmium, chromium, lead, nickel, etc.), radioactive substances, etc. in water. It is the earliest and most widely used water purification material in water purifiers. Activated carbon has a well-developed pore structure and strong adsorption capacity.
Activated carbon has the function of sewage treatment
The environmental protection industry is used for sewage treatment, waste gas and harmful gas treatment, and gas purification of the main air pollutants emitted during the coal combustion process in my country. Activated carbon has good desulfurization and denitrification treatment effects, low investment and operating costs, and is easy to recycle. .
Activated carbon has adsorption
Activated carbon adsorption to remove indoor pollution is the most widely used, most mature, safest, most reliable, and most absorbent method. Activated carbon has attracted more and more attention as an excellent physical and chemical adsorbent. The activated carbon pack can absorb formaldehyde, ammonia, benzene, xylene, radon and other indoor harmful gas molecules in the air, and quickly eliminate decoration odors.
Activated carbon has the effect of deodorizing furniture
Activated charcoal can also be placed on newly purchased furniture to remove odors.
Activated carbon has the effect of deodorizing the car
There will be many harmful and unpleasant pungent smells in the new car, which can be removed by using activated carbon at this time.
Activated carbon is used in a wide variety of applications including water and air purification, gas masks, industrial processes and medical. Its high surface area and adsorption capacity allow it to effectively remove impurities, pollutants and toxins from liquids and gases.
