The role of activated carbon in guiding healthy environmental living

With the acceleration of industrial progress, the number of pollutants in the air is increasing, and people's awareness of environmental protection is also increasing.Activated carbon strong adsorption, favored by people, the activated carbon role what?Today we'll take a look at what activated charcoal does.

What is activated carbon

Activated carbon is also known as active carbon black, is black powder or granular amorphous carbon, activated carbon in addition to carbon in addition to the main components of oxygen, hydrogen and other elements.Activated carbon is a kind of porous carbon with low bulk density and large specific surface area because of its irregular arrangement of microcrystalline carbon and the pores between the cross-connections.Activated carbon odorless, tasteless, sand free, insoluble in any solvent, to a variety of gases selective adsorption capacity, to organic pigments and nitrogenous alkali has a high capacity adsorption capacity.The total surface area per g can reach 500 ~ 1000m2, the relative density is about 1.9 ~ 2.1, and the apparent relative density is about 0.08 ~ 0.45.

The action of activated carbon

1. In the process of preparing pure water and drinking water, activated carbon has become an indispensable means to remove residual chlorine. It has the characteristics of high removal efficiency, no secondary pollution and simultaneous removal of organic matter in water.Activated carbon adsorbs residual chlorine, its adsorption performance mainly depends on the adsorption capacity and adsorption rate, both are indispensable;It is required to obtain a high adsorption capacity in a short contact time, that is, a high adsorption rate, instead of simply emphasizing the size of the adsorption capacity.

2. Activated carbon used for air purification has developed void structure and abundant micropore tissue, which has a strong adsorption field. When toxic and harmful gases in the air come into contact with activated carbon, the strong adsorption field of activated carbon micropore can adsorb molecules with toxic and harmful substances into the micropore.When using activated carbon to purify the air, in order to give full play to the effect of activated carbon, people often force need to purify the air, through made of active carbon filter device, the air pollution can be fully contact with activated carbon, activated carbon internally developed micropore, can quickly, completely and thoroughly adsorption toxic or harmful gases in the air, the air purifying purpose to protect the safety of the human body.

Activated carbon use

Activated carbon is a commonly used adsorbent, catalyst or catalyst carrier.According to the raw material source, activated carbon can be divided into wood activated carbon, fruit shell activated carbon, animal bone/blood activated carbon, mineral raw carbon, synthetic resin activated carbon, rubber/plastic activated carbon, recycled activated carbon, etc.Activated carbon can be divided into powder, granular, irregular granular, cylindrical, spherical and fibrous, etc.

Activated carbon is widely used in almost all sectors of the national economy and People's Daily life, such as water purification, gold extraction, decolorization of sugar solution, drug injection refining, blood purification, air purification, human safety and protection.
