| description | Micro-meso or micro-macro porous bead carbons and their use in novel processes for the removal of pesticides or pharmaceutical residues from drinking water are provided. In particular it is applicable to removal of water-soluble compounds that cannot be readily treated using conventional adsorbents. The invention provides a process for treating water contaminated with pesticide or pharmaceutical residues which comprises contacting the contaminated water with a micro-porous, micro-mesoporous or micro-macro-porous carbon with very little heteroatom surface functionality that has been activated in carbon dioxide to minimise the introduction of surface oxygen functionality
L'invention concerne des billes de carbone micro-mésoporeuses ou micro-macroporeuses et leur utilisation dans de nouveaux procédés pour éliminer les pesticides ou les résidus pharmaceutiques de l'eau potable. L'invention s'applique particulièrement à l'élimination de composés hydrosolubles qu'il n'est pas possible de traiter par des adsorbants conventionnels. L'invention concerne un procédé de traitement d'eau contaminée par des pesticides ou des résidus pharmaceutiques consistant à mettre an contact l'eau contaminée avec du carbone microporeux, micro-mésoporeux ou micro-macroporeux avec une fonctionnalité de surface hétéroatome très petite activée dans du dioxyde de carbone pour réduire l'introduction de fonctionnalité d'oxygène de surface. |
