Activated Charcoal Review Sheet [ permanent dead link], USDA Organic Materials Review, February 2002. Activated carbon is carbon produced from carbonaceous source materials such as bamboo, coconut husk, willow peat, wood, coir, lignite, coal, and petroleum pitch. It can be produced (activated) by one of the following processes:

Residual organic gasification by a non-oxidising gas (steam or carbon dioxide) at elevated temperatures (800°C (1,470°F))Research is being done testing various activated carbons' ability to store natural gas [1] [2] and hydrogen gas. [1] [2] The porous material acts like a sponge for different types of gases. The gas is attracted to the carbon material via Van der Waals forces. Some carbons have been able to achieve bonding energies of 5–10 kJ per mol. The gas may then be desorbed when subjected to higher temperatures and either combusted to do work or in the case of hydrogen gas extracted for use in a hydrogen fuel cell. Gas storage in activated carbons is an appealing gas storage method because the gas can be stored in a low pressure, low mass, low volume environment that would be much more feasible than bulky on-board pressure tanks in vehicles. The United States Department of Energy has specified certain goals to be achieved in the area of research and development of nano-porous carbon materials. All of the goals are yet to be satisfied but numerous institutions, including the ALL-CRAFT program, [1] [2] [23] are continuing to conduct work in this field. Diyuk, V. E.; Zaderko, A.

Some carbons have a mesopore (20 Å to 50 Å, or 2 to 5nm) structure which adsorbs medium size molecules, such as the dye methylene blue. Activated carbon can be used as a substrate for the application of various chemicals to improve the adsorptive capacity for some inorganic (and problematic organic) compounds such as hydrogen sulfide (H 2S), ammonia (NH 3), formaldehyde (HCOH), mercury (Hg) and radioactive iodine-131( 131I). This property is known as chemisorption.

[37] To create your simple filter for scientific purposes, you will need very similar materials. These materials include: Once you have the materials you need in place, creating your filter is simple. You will want to follow these basic steps to create a basic charcoal filter:

Activated carbon is commonly used on the laboratory scale to purify solutions of organic molecules containing unwanted colored organic impurities.

Environmental [ edit ] Activated carbon is usually used in water filtration systems. In this illustration, the activated carbon is in the fourth level (counted from bottom). Oxidation in the liquid phase is caused by a wide range of reagents (HNO 3, H 2O 2, KMnO 4). [57] [58] [59] However, in the case of using activated carbon for adsorption of minerals such as gold, the particle size should be in the range of 3.35–1.4 millimetres (0.132–0.055in). Activated carbon with particle size less than 1mm would not be suitable for elution (the stripping of mineral from an activated carbon).As mentioned, activated charcoal filters attract and adsorb unhealthy organic compounds, but allow other minerals to remain in the water. Unfortunately, this also means not all microorganisms are removed, and charcoal is often used along with other filters.

A common issue many have is that they do not like the taste of tap water, believe it tastes metallic, or do not like the aroma of the water. The taste of tap water is often due to chlorine and other additives that are put in place to kill off bacteria. While adding chlorine is a great way to protect public health, it has greatly impacted the number of individuals who drink tap water regularly. As water passes through the carbon media, the contaminants are held within deep fissures, on the surface or are altered by the catalytic action of the media. Deciding whether or not to use a carbon filter in your home and the type of filter you need all depends on the type(s) and contaminants’ concentration levels in your water. You can install one in case one or more of the toxic pollutants that activated carbon filters remove or reduce pop up uninvited in your water supply.
