What are the applications of activated carbon?
Posted On 10/15/2020 04:07:12 by dingxinda9

Activated carbon is used in gas purification, decaffeination, gold purification, metal extraction, water purification, medicine, sewage treatment, air filters in gas masks and respirators, filters in compressed air and many other applications.buy bulk activated carbon pellets

 

One major industrial application involves use of activated carbon in the metal finishing field. It is very widely employed for purification of electroplating solutions. For example, it is a main purification technique for removing organic impurities from bright nickel plating solutions. A variety of organic chemicals are added to plating solutions for improving their deposit qualities and for enhancing properties like brightness, smoothness, ductility, etc. Due to passage of direct current and electrolytic reactions of anodic oxidation and cathodic reduction, organic additives generate unwanted breakdown products in solution. Their excessive build up can adversely affect the plating quality and physical properties of deposited metal. Activated carbon treatment removes such impurities and restores plating performance to the desired level.

 

Medical Applications:

Activated carbon is used to treat poisonings and overdoses following oral ingestion. It is not effective for a number of poisonings including with: strong acids or alkali, iron, lithium, arsenic, methanol, ethanol or ethylene glycol.

 

Incorrect application (e.g. into the lungs) results in pulmonary aspiration which can sometimes be fatal if immediate medical treatment is not initiated. The use of activated carbon is contraindicated when the ingested substance is an acid, an alkali, or a petroleum product.

 

Analytical chemistry applications

Activated carbon, in 50% w/w combination with celite, is used as stationary phase in low-pressure chromatographic separation of carbohydrates (mono-, di-trisaccharides) using ethanol solutions (5- 50%) as mobile phase in analytical or preparative protocols.

 

Gas purification

Filters with activated carbon are usually used in compressed air and gas purification to remove oil vapours, odour, and other hydrocarbons from the air. The most common designs use a 1 stage or 2 stage filtration principle in which activated carbon is embedded inside the filter media.Activated carbon is also used in spacesuit Primary Life Support Systems. Activated carbon filters are used to retain radioactive gases from a nuclear boiling water reactor turbine condenser. The air vacuumed from the condenser contains traces of radioactive gases. The large charcoal beds absorb these gases and retain them while they rapidly decay to non-radioactive solid species. The solids are trapped in the charcoal particles, while the filtered air passes through.

 

Chemical purification

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

 

Sound Absorption

Activated carbon can filter air and water. Sound energy is found within air and water and activated carbon can be used to absorb that energy. With its high degree of porosity in each activated carbon granule, sound energy has numerous areas to enter into and be converted to heat. With the energy change to heat, the process of sound absorption occurs.

 

Activated carbon in its granule form can be used to absorb middle and high frequency ranges provided the absorbers design lets air pass through the carbon. Activated carbon can also be used inside of diaphragmatic absorption technology to increase the rate of absorption within the diaphragmatic absorber.activated charcoal wholesale price
