Activated Carbon Adsorption
Activated carbon is a remarkable material widely used in water purification due to its unique porous structure and excellent adsorption properties.
It is typically made from materials such as coconut shells, coal, or wood.
Through a series of physical and chemical activation processes, these raw materials are transformed into activated carbon with an extremely high surface area.
The structure of activated carbon is full of tiny pores, which can be classified into micropores, mesopores, and macropores.
This large surface area allows activated carbon to come into contact with a vast amount of water molecules and contaminants within the water.
One of the main functions of activated carbon in water purifiers is to remove chlorine and its by – products.
Chlorine is commonly added to tap water for disinfection purposes.
Activated carbon removes chlorine through a combination of physical adsorption and chemical reactions.
The unsaturated bonds and surface functional groups on the activated carbon can react with chlorine molecules or hypochlorous acid (HOCl) present in water.
