The development history of activated carbon
Prior to the invention of activated carbon as a patent in the early twentieth Century, there was a history of documented and many references to the history of charcoal applications.In 3750 BC, it was known to the Egyptians and Sumerians that the earliest use of charcoal.In the 1550 BC, ancient Egypt had charcoal as a medical record.The Greek doctor F Pokela di (Hippocrate) and Pliny (460-359 BC) with charcoal treatment of epilepsy and anthrax.In 450 BC, the Phoenician merchant ship recent research shows that drinking water is stored in wooden barrels burning in. It is the storage method of marine drinking water in history until eighteenth Century.During the same period, Hindu religious documents also mentioned the use of sand and charcoal to filter and purify drinking water.
157 years, Claudius medical papers mentioned in the vegetable and animal sources prepared charcoal, for the treatment of various diseases.Chinese Li Shizhen of the Ming Dynasty (A.D. 1518-1593) edited by Compendium of Materia Medica mentioned in charcoal for treatment of diseases.In 1773, Scheler through a large number of experiments found charcoal adsorption capacity and adsorption of various gases.In 1777, the effect of charcoal heating and gas adsorption was reported, which led to the "condensation adsorption theory".In 1785, Scheler studied charcoal adsorption gas, the adsorption capacity of steam from the steam to a series of organic chemicals and a variety of aqueous solutions using charcoal decolorization, especially the production of tartaric acid commercial applications. This seems to be the first systematic consideration of the adsorption of charcoal on the liquid phase.
