Activated carbon (or charcoal) is a porous form of carbon commonly used for adsorption and in chemical reactions. The microposority increases its surface area significantly. Adsorption properties are usually enhanced by chemical treatment. Alternatives that work in the same manner are activated coal and coke. There are a number of things relating to activated carbon Philippines residents need to know.
A number of raw materials are available to be used as a source of carbon. They include, among others, coconut husks, nutshells, petroleum pitch, wood and peat among others. There are two main options of activation: a physical process and a chemical one. During physical activation, the raw materials are burned with hot gases in air. The temperature needed for this is anything between 600 and 1200 degree Celsius.
In chemical activation, the source materials are first impregnated with certain chemicals. Such chemicals may be strong acids, alkalis or salts. Examples include sodium hydroxide, zinc chloride, phosphoric acid and calcium chloride among others. Carbonization us then done at temperatures of between 450 and 900 degrees Celsius. Generally, the chemical driven alternative is preferred over the physical process due to the lower temperatures and the shorter duration of time involved.
Activated carbon plays a major role in the medical field. One of the main indications is in the management of over dosage and poisoning related to acids, alkalis, arsenic, lithium, methanol and cyanide among others. The charcoal can be obtained from the pharmacy as an over the counter drug. It is important to be cautious when taking it because it may lead to aspiration pneumonitis if it ends up in the lungs.
Active charcoal is used for a number of different industrial applications. These mainly related to processes involved in removing pollutants from water sources and air. Specifically, these may include spill clean ups, remediation of ground water, drinking water filtration and the capture of volatile organic compounds (VOCs) among others. As it purifies the air, the carbon may have an additional role in determining radon concentration levels.
Active charcoal is classified in a number of ways depending on physical attributes and uses. Some of the physical properties that may be used include the iodine number, the surface area, the density, ash level and the mesh size among others. Powdered activated charcoal is made of granules less than 1 millimeter in diameter and is mainly used in process units such as clarifiers and gravity filters among others. Granular charcoal has larger particles and us mainly used in water treatment and deodorization.
Active charcoal plays a vital role in mercury scrubbing. This is necessary in medical incinerators and power plants that are powered by coal. The charcoal is first impregnated with iodine or sulfur to make it most effective for this purpose. The resultant compound is then disposed of in a landfill.
Activated carbon has many more uses. Ongoing research shows that there is great potential for the uses to increase in areas such as the medical and agricultural fields. Due to the differences that exist in the types, it is important that one talks to an expert to get recommendations on the most appropriate type of charcoal to be used in a given situation.
