An Analysis of Activated Carbon

Activated carbon is a type of carbon that has a very wide surface area available for chemical reactions and absorption obtained from charcoal. It is developed to be very porous, and therefore capable of achieving a high degree of absorption. It is also known as carbon “Active”. Checking for absorption of nitrogen gas typically determines the microporosity of activated carbon. Usually, one gramme of this material has a surface area of 500m2. Although normal ones have a very high surface area, more of the carbon’s absorbing characteristics can be created by additional chemical treatment. Some of the commercial uses are: purification of water, medication, extraction of metals, treatment of waste, air philtres and gas masks. For more details click Pacific Coast Carbon LLC.

Activated carbon is one of the most effective uses of eliminating toxins from the water and air. It can be used in both chemical plant spill cleanup and air purification. It may also be used in the remediation of groundwater and filtration of drinking water. The cleanup of volatile organic compounds ( VOCs) used in paint, dry cleaning, gasoline and other chemical products is another application.

In the metal finishing industry maybe the most common use of activated carbon is. It is used for electroplating solution purification, such as the removal of organic impurities from nickel. In metal plating, several organic chemicals are used to enhance their deposit properties, such as ductility, brightness and smoothness. Unfortunately, some of the organic additives produce toxic byproducts when an electrical current is passed through the metal to apply these chemicals. The plating integrity and physical condition of these metals may be harmfully affected by an excessive buildup of these by-products. Using activated carbon fixes those impurities and restores the efficiency of plating to a working level.
