A carbon chloroform extract (CCE) is a chemical procedure in which the organic compounds in water are adsorbed by activated carbon and then desorbed by the solvent chloroform. A carbon chloroform extract can measure trace amounts of possibly toxic organic compounds. Its purpose is to remove (and possibly measure) the amount of organic matter in water.
During the carbon chloroform extract procedure (CCE), the pores in activated carbon acts as a sieve (filter) and a magnet of contaminants in the purification process.
Bituminous coal, the carbon source, is first crushed into small pieces. Binders are later used to give it hardness. The carbon-rich raw material is placed in bakers at a low temperature and eventually placed in a high-temperature furnace.
The adhesive forces inside the carbon are high; hence any contaminants will remain trapped inside. Chemical reactions between carbon and any contaminants usually occur, so the carbon performs both physical and chemical filtering. The size of the particles absorbed can be measured in microns.
Once the matter is adsorbed by activated carbon from a stream of water, it is then extracted from the activated carbon with chloroform, using a specific standardized procedure.
Fluid purification prevents contaminants from acting as corrosion agents.
