Abstract[English]
A surfactant containing activated carbon-based media for efficient removal of volatile organic compounds (VOCs) from water and air. The media is prepared by treating porous activated carbon with an oxidizing agent to render oxidized activated carbon, which is then soaked in a surfactant containing solution. The surfactant impregnates into the pores and on 5 surfaces of the oxidized activated carbon to render surfactant impregnated activated carbon that is capable of enhancing reduction of VOCs. The surfactant impregnated activated carbon media may be made into filter blocks or provided into filter cartridges.[French]

Le milieu est préparé par traitement de charbon actif poreux avec un agent oxydant pour rendre le charbon actif oxydé, qui est ensuite trempé dans une solution contenant un tensioactif. Le tensioactif s'imprègne dans les pores et sur 5 surfaces du charbon actif oxydé pour rendre le charbon actif imprégné de tensioactif qui est apte à améliorer la réduction des COV. Le milieu de charbon actif imprégné de tensioactif peut être transformé en blocs de filtre ou disposé dans des cartouches de filtre.
