The primary raw material used for making activated carbon is any organic material with a high carbon content (coal, wood, peat, coconut shells). Granular activated carbon mediais most commonly produced by grinding the raw material, adding a suitable binder to give it hardness, re-compacting and crushing to the correct size. The carbon-based material is converted to activated carbon by thermal decomposition in a furnace using a controlled atmosphere and heat. The resultant product has an incredibly large surface area per unit volume, and a network of submicroscopic pores where adsorption takes place. The walls of the pores provide the surface layer molecules essential for adsorption. Amazingly, one pound of carbon (a quart container) provides a surface area equivalent to six football fields.
What else can I help you with?
Specific gravity of granular activated carbon filter media?
approximately 1.40
Carbon black definition?
A carbon product obtained from liquified carbon feedstock and used mainly in the rubber industry.
Can all types of compounds be purified by activated carbon?
No, this is not a general valid method.
Is there carbon atoms in a pickle?
Naturally. Carbon atoms are present in everything that are organic or are organic derivatives. In any substance obtained from plants or animals, carbon atoms are naturally present.
What is the last step in the sequence of events when cyclic AMP acts as a second messenger?
the last step is ofcourse glycogen breakdown.......before that inactive glycogen phosphorylase-b is activated and phosphorylated to glycogen phosphorylase-a by the help of activated phosphorylase kinase........ ......phosphorylase kinase was activated by activated protien kinase..and activated protien kinase was activated by cyclic amp...........
What is the pH for activated carbon?
Activated carbon hasn't a pH.
Why activated carbon is called activated?
Activated carbon has high surface area; this characteristic improve the reactivity of the material.
What does the company Calgon Carbon offer?
The company Calgon Carbon offers the following services: Activated carbon and speciality products, activated carbon absorption equipments, activated carbon reactivation or recycling, ultraviolet technologies, ion exchange technology systems.

Are activated carbon and charcoal the same?
Activated carbon and charcoal are not the same. Charcoal is a type of carbon made from burning wood or other organic materials, while activated carbon is a specially processed form of charcoal that has been treated to increase its surface area and make it more effective for adsorption.
Is activated carbon soluble?
No, activated carbon is not soluble in water or other solvents. It works by adsorbing (not absorbing) impurities and contaminants onto its surface.
Why should you add activated carbon to a cool solution and reheat it to boiling?
Adding activated carbon to a cool solution and reheating it to boiling helps to activate the carbon, which increases its absorptive properties. This process helps remove impurities and contaminants from the solution by adsorption onto the activated carbon, resulting in a cleaner final product.
What are the differences between carbon and activated carbon, and how do they affect their respective uses in various applications?
Carbon is a chemical element found in various forms, while activated carbon is a processed form of carbon with increased surface area and adsorption capabilities. The differences lie in their structures and properties, with activated carbon being more porous and effective at adsorbing impurities. This makes activated carbon suitable for applications like water purification, air filtration, and gas adsorption, where its enhanced adsorption capacity is beneficial.
