CARBON PURIFICATION
To purify the carbon from the smoke emitted by factories, the students of class IX namely
J.NITHIN and ARNAV.U had created a model for " CARBON PURIFICATION" and displayed in the CBSE - REGIONAL SCIENCE EXHIBITION held at RMK senior secondary school ,Thiruverkadu.

This model has applications wherever air pollution needs to be controlled or filtered, especially in factories, vehicles, indoor spaces, and industrial settings. It also serves as a great educational tool to explain the importance of environmental protection.
Carbon purification uses activated carbon to remove impurities from liquids and gases, like water and air, through a process called adsorption. The highly porous structure of activated carbon traps contaminants on its surface, effectively eliminating issues such as odors, chlorine, organic compounds, and other chemicals. This purification technique is widely used in residential water filters, industrial water treatment, and air purification systems to improve product quality and remove pollutants.
PROCEDURE
1. Take a cardboard box and place it in a cardboard of length 1 feet x 2 feet.
2.Now, pierce a hole in the top of the cardboard box.
3. Take the plastic water bottle and cut the water bottle into a half.
4.Now, open the cardboard box and insert the top body of the water bottle
. 5. Fix the bottle carefully as the node of the water bottle can be seen from outside.
6.And then insert a PVC pipe into the mouth of the water bottle.
7.Now, take a transparent plastic box and pierce two holes in opposite directions.
8. Insert one end of the polluted air pipe into one side hole of the plastic box.
9. Ensure the connection is airtight using tape or glue.
10. Take another pipe and insert it into the opposite side hole of the plastic box.
11. Take the chicken mesh and fold it like a box and keep it inside the plastic box.
12. Fill the chicken mesh with cotton
13. Now, take a vertical pipe and connect it.
14. Paste that pipe in a vertical direction.
15. And then connect the PVC pipe from the mouth of the water bottle to the plastic box.
16. Now, label all the parts as factory, polluted air, carbon absorber, clean air, and chimney.
17. Take a lamp and place it inside the cardboard box.
18. Place camphor inside the lamp and fire it.
WORKING EXPLANATION
Polluted air exits the factory through the first pipe.
It enters the carbon absorber, where the cotton filters out pollutants.
The clean air exits through the second pipe and goes up the chimney.
Observation
Smoke Generation: Burning camphor produce white smoke, representing polluted air inside the factory.
Movement of Polluted Air: The smoke will travel through the "Polluted Air" pipe leading out of the factory and into the carbon absorber.
Filtering in Carbon Absorber: The smoke passes through the cotton and observes the carbon. The intensity of the smoke reduces, indicating partial or complete removal of pollutants.
Clean Air Release: The relatively cleaner air (with less visible smoke) exits through the "Clean Air" pipe and moves out via the chimney.
BENEFITS
Implementing a carbon purification model offers benefits like removing harmful organic chemicals, improving water taste and odor, and enhancing product quality in industries like food and pharmaceuticals. It also protects sensitive equipment, such as RO membranes, and leads to reduced operational costs through its low energy use and long service life. In environmental contexts, it aids in capturing atmospheric carbon dioxide, which can then be stored in water or used for applications like water softening or cooling systems.
