Since Roman times, activated carbon has been used to remove harmful impurities in water, such as organic pollutants. Activated carbon is a general term used to describe a series of carbonaceous adsorbents with highly amorphous forms and widely developed internal pore structures.Activated carbon is very porous and has a large surface area, which makes it an effective adsorption material. Compared with the actual size of
[u]activated carbon pellets[/u], the larger surface area makes it easier to remove a large number of impurities in a relatively small closed space. Interestingly, the product has a strong connection with the humble coconut. Coconut shells are used to make commercially significant trade-offs, including activated carbon. In fact, activated carbon processed from coconut shell is considered to be superior in quality to activated carbon processed from other sources, mainly due to the large pores in the structure.
Activated carbon is a non graphite form of carbon, which can be made from any carbonaceous material, such as coal, lignite, wood, rice husk, coconut shell pulp, coconut shell, etc. Charcoal is produced from coconut shell, while activated carbon is activated by steam, which increases surface area and absorption capacity. Activated carbon is widely used in refining and bleaching of vegetable oils and chemical solutions, water purification, recovery of solvents and other vapors, recovery of gold, protection of toxic gases in gas masks, and active carbon used in filters to provide adequate protection against war gases.
Application of activated carbon
Water filter element: the water filter uses fine physical barriers, chemical or biological processes to remove impurities by minimizing water pollution.
Drug: purity is very important in drug production. This applies to all stages, from raw materials to intermediates to final products. The unique properties of specific activated carbon (e.g.
[u]wood activated carbon[/u]) are excellent for removing color compounds, odorants, proteins and other contaminants that may be present in raw materials or formed during production.
Catering: beverage manufacturers rely on activated carbon to remove bad tastes and odors and help ensure the long-term stability of their products. Activated carbon products are also used to improve the quality of beverages, from water to juice to distilled wine, to make them look good, smell good and taste good.
Cars: activated carbon canisters reduce hydrocarbon emissions from gasoline powered cars and trucks. Moreover, many cars now include an air purification system that uses activated carbon in their cabin air filters.
Water treatment / seawater distillation: activated carbon is widely used in water treatment to remove free chlorine and / or organic compounds. Removal of organics from drinking water may be to prevent the reaction of common organic acids (such as humic acid or fullerenes) with chlorine to form trihalomethanes (a known carcinogen), or to treat wastewater to remove any amount of organic compounds to make the water suitable for unloading.
