Title (EN) DUAL IMPREGNATED ACTIVATED CARBON
(FR) CHARBON ACTIF A DOUBLE IMPREGNATION
Abstract: front page image
(EN)A dual-impregnated activated carbon composition includes activated carbon impregnated with a Group 6-12 metal salt and a Group 1 metal carbonate salt, where the molar ratio on the activated carbon of the Group 1 metal to the Group 6-12 metal is 1 or greater. The dual-impregnated activated carbon composition is particularly suitable for filtering gaseous contaminants.
(FR)Une composition de charbon actif à double impregnation comprend du charbon actif imprégné d'un sel métallique des groupes 6 à 12 et un sel de carbonate métallique du groupe 1, le rapport molaire entre le charbon actif contenant le métal du groupe 1 et celui contenant le métal des groupes 6 à 12 étant égal ou supérieur à 1. Cette composition de charbon actif à double imprégnation est particulièrement utile pour filtrer des contaminants gazeux.
