A “dislike” of water.
Attraction to the Activated carbon.
Activated carbon adsorption proceeds through three basic steps:
Substances adsorb to the exterior of the carbon surface,
Substances move into the carbon pores
Substances adsorb to the interior walls of the carbon. Many organic compounds such as chlorinated and non-chlorinated solvents, triholmethanes, pesticides and VOC are adsorbed into the inner pores. Activated carbon is also effective in removal of chlorine and moderately effective for removal of some heavy metals.
