Activated carbon is a kind of black porous solid carbon, which is produced by pulverizing, forming or carbonizing and activating coal with uniform coal particles. The main component is carbon, and contains a small amount of oxygen, hydrogen, sulfur, nitrogen, The specific surface area of ordinary activated carbon is between 500 and 1700m²/g. It has strong adsorption performance and is an industrial adsorbent with a wide range of uses.
Charcoal with strong adsorption capacity is made by burning hardwoods, nut shells, bones, etc. in a closed container to increase the pores. Gas masks are used to filter gases, industrially used to decolorize and purify solutions, and medicinally to absorb toxins, bacteria or gases in the gastrointestinal tract.
basic introduction Activated carbon is a traditional and modern man-made material, also known as carbon molecular sieve. Chemical formula: C. CAS: 64365-11-3 EINECS: 264-846-4. Since its inception a hundred years ago, the application fields of activated carbon and honeycomb activated carbon have been expanding, and the number of applications has continued to increase.
Activated carbon is mainly used to remove trace pollutants in wastewater to achieve the purpose of deep purification. It has a good decolorization effect on dye wastewater, and can also adsorb and containing compounds, but its adsorption capacity is limited, and it is only suitable for treating containing compounds. low waste water. Activated carbon for treating chromium-containing wastewater has stable adsorption performance, high treatment efficiency, low operating cost, and has certain social and economic benefits. Therefore, the treatment of chromium-containing wastewater with activated carbon has been widely used.
