WebAug 23, 2024 · Activated carbon is commonly used to adsorb natural organic compounds, taste and odor compounds, and synthetic organic chemicals in drinking water treatment systems. Adsorption is both the physical and chemical process of accumulating a substance, such as PFAS, at the interface between liquid and solids phases. Webfrom the time before adsorption became understood in the 1920's. A better term is “activated carbon.” Carbon is activated by the pyrolysis of coal, wood, bark, coconut husks, etc. to remove all the volatile material as a gas or vapor, and leave only the carbon. This carbon might then also be partially oxidized to enlarge its pores.
