Abstrakt: Water pollution remains a serious problem. Adsorption technology is currently being used in large scale for the removal of such pollutants from wastewaters. Among the different existing systems adsorbent for the removal of pollutants from wastewaters, activated carbon powder (ACP) is the most widely used one in developed countries. The adsorption of organochlorine pesticides onto ACPs, is established to be the most effective and reliable method for the removal of organic pesticides. We used ACP for the adsorption of Lindane from hexane solutions as a first step in order to gain some insights about the sorption abbility of this material and to compare it after the surface modification step with organic layer. The ACP powder modified by the reduction of different synthesized diazonium salts. The adsorption performance of ACPand covalently modified ACP toward the Lindane (gamma-hexachlorocyclohexane, ?-HCH) was evaluated through the use of GC-ECD technique. The obtained results point out that ACP is a very promising adsorbent for the wastewater treatment. [ABSTRACT FROM AUTHOR]
