Purification by activated carbon is a proven, modern, or even more; a spoonful of activated state of the art technology for a multitude of purification carbon easily equates the surface needs. Nevertheless, the principles have been discovered area of a soccer field. long back, and activated carbon has had a rich history ever since. The ancient Greeks had already described the use It is in the activation process that of to soften the effects of food poisoning. And at this surface area is created. The the time of Columbus sailors used to blacken the insides most common process is steam of water barrels with fire. They had learned that the water activation; at around 1000 °C steam would stay fresh much longer by doing so. molecules selectively burn holes into the carbonised raw material, This beneficial behaviour of carbonised materials is thus creating a multitude of pores caused by the phenomenon that contaminants, organic inside the carbonaceous matrix.
