Activated carbon or activated charcoal is usually a kind of carbonaceous material, which has been identified as having a high surface area, especially the adsorption of nitrogen is very high. Because it has a small hole (micropore) and can be further improved by using conditioning chemicals.
Activated carbon is a kind of charcoal with special properties, which has been enhanced or enhanced by using science and technology to obtain its properties or power. granular activated carbon Because of its high porosity and pore size, it has a large number of micro pores. According to the production process and purpose, different types of raw materials will be used to produce activated carbon.
Raw materials used are usually organic, consisting of carbon and hydrogen, and the most common is cellulose in plants and trees (e.g., wood, rubber, bamboo, waste wood). And agricultural wastes, such as rice husk, coconut shell and sawdust, produced by high temperature incineration in closed environment.
Activated carbon is used to filter out unwanted organic compounds from liquids or gases, such as in purified drinking water. coconut shell carbon Various industries need purified water and wastewater treatment for bleaching, chemical separation and preparation of various liquids, experimental medicine, detoxification, blood purification, etc., and can filter harmful odors and gases in masks, filters, toxins and air purifiers.
