The Many Uses Of Activated Carbon
Total Articles: 6
Raw materials like coconut shell, coal, lignite, wood, coir pith and rice husk etc are carbonaceous in nature. And from these materials activated carbon is made. It is also a form of carbon but is non-graphite and micro-porous. The most high quality activated carbon is derived from coconut shell. Activated carbon is usually used in home filters. It helps in removing and filtering water borne impurities effectively. Its properties are similar to different types of organics and dissolved chlorine and have incredible absorption capacity. Another plus point is that activated carbon can be custom made for specific requirements.
Actually all organic materials having high content of coal, peat, wood and coconut shell can be used to manufacture activated carbon. When derived from charcoal, it is known as activated charcoal and it is highly porous.
The surface area of this carbon is large and is ideal for adsorption and chemical reactions. Moreover it possesses a high degree of micro-porosity and when determined through nitrogen gas adsorption, the surface area of one gram of activated carbon is equivalent to 2.17 tennis courts. The adsorbing capacity can be further accelerated through advance chemical treatment. To transform carbon based materials mentioned above into activated carbon, the same is put through thermal decomposition process vide heat and atmosphere controlled heat furnace.
There are various usages of activated carbon. It is mainly used to remove odors and chemicals from water. It is also used to remove hydrogen sulphide which is a pungent smelling organic gas from water. Other usages are removal of iron, chelated copper and mercury, absorbing chlorine from water and removal of VOC (volatile organic chemicals) like benzene, pesticides, radon, herbicides and similar solvents/compounds.
Activated carbon acts as a purifying and de-colouring agent in different processes. It can absorb up to 90% impurities from different types of Aquarius solutions. Generally this material is widely used to treat water, combat odor and to detoxify. In fact, you simply cannot do without it for these processes. There is a huge demand for this material as it is used in various application areas. Nowadays it is available in various forms like granule and fine powder form etc. If you want to know
where to buy activated carbon you can try out local chemical stores in your area or browse the internet where you will find many online stores that sell activated carbon.
When used to treat water, its main objective is to make the water safe for consumption. This is very important in today’s context when availability of pure, clean and safe drinking water is a major concern in many countries. Direct consumption of water is out of question due to rampant air and water pollution. In such a scenario, using activated carbon for water treatment is the most viable option. Compared to traditional filtration methods which has many flaws, the amazing properties of this element provides safe drinking water in the most cost-effective and natural manner. Apart from removing various water pollutants, it also removes foul odors from water.
