Due to passage of direct current and electrolytic reactions of anodic oxidation and cathodic reduction, organic additives generate unwanted breakdown products in solution. A variety of organic chemicals are added to plating solutions for improving their deposit qualities and for enhancing properties like brightness, smoothness, ductility, etc. For example, it is the main purification technique for removing organic impurities from bright nickel plating solutions. One major industrial application involves use of activated carbon in metal finishing for purification of electroplating solutions. Activated coke is derived from coke.Īctivated carbon is used in methane and hydrogen storage, air purification, capacitive deionization, supercapacitive swing adsorption, solvent recovery, decaffeination, gold purification, metal extraction, water purification, medicine, sewage treatment, air filters in respirators, filters in compressed air, teeth whitening, production of hydrogen chloride, edible electronics, and many other applications. When derived from coal it is referred to as activated coal. These bulk sources are converted into charcoal before being 'activated'. Further chemical treatment often enhances adsorption properties.Īctivated carbon is usually derived from waste products such as coconut husks waste from paper mills has been studied as a source. An activation level sufficient for useful application may be obtained solely from high surface area. Charcoal, before activation, has a specific surface area in the range of 2.0–5.0 m 2/g. Activated is sometimes replaced by active.ĭue to its high degree of microporosity, one gram of activated carbon has a surface area in excess of 3,000 m 2 (32,000 sq ft) as determined by gas adsorption. Activation is analogous to making popcorn from dried corn kernels: popcorn is light, fluffy, and its kernels have a high surface-area-to-volume ratio. It is processed (activated) to have small, low-volume pores that increase the surface area available for adsorption (which is not the same as absorption) or chemical reactions. We provide a diverse range of products, in a variety of different sizes and pore structures, manufactured from raw materials that include coconut shell, wood, and coal.Activated carbon, also called activated charcoal, is a form of carbon commonly used to filter contaminants from water and air, among many other uses. The basic mechanism through which activated carbon removes impurities from gases or liquids through the attraction of molecules into this network of pores is referred to as adsorption.Įaupure Chemicals offer high-grade activated carbon is suitable for water and air purification. These carbon layers are stacked unevenly, creating a structure with various shaped and sized cavities between the carbon layers. Its network of pores within a rigid carbon skeleton consists of disordered layers of carbon atoms which are linked together by random chemical or carbon bonds.Īdsorption is the key to the performance of activated carbon. Manufactured by chemical or high temperature steam activation, this highly porous adsorptive medium has a complex structure that is composed primarily of carbon atoms. The primary raw material used for activated carbon is any organic material with a high carbon content like coconut shell, wood and coal. Please refer Technical Data Sheet, Label and MSDS for more details and shelf life.Īctivated carbon Powder is used to purify liquids and gases in a variety of applications, including municipal drinking water, food and beverage processing, odour removal, industrial pollution control, etc. This product should be stored in original containers in cool and dry place, away from sources of heat, flame and direct sunlight. In case of splashing into the eyes, flush it with fresh water and obtain medical attention. Splashes on skin should be washed off with water immediately. Proper human safety products such as Splash goggles, lab coat, vapor respirator, gloves and boots should be worn while handling and applying chemicals. There are various grades of activated carbon available depending upon mesh size, iodine content, acid volume etc.Īctivated CarbonGranular contains less Iron, Ash, Acid soluble matter & Water-soluble matter. Water filtration, cosmetic, Industrial furnacesĪctivated Carbon Powder are used for water purification in ACF (Activated Carbon Filter).
