Title
(EN) METAL ION-MODIFIED MATERIALS FOR ODOUR REMOVAL AND CONTROL
(FR) MATÉRIAUX MÉTALLIQUES À IONS MODIFIÉS POUR L’ÉLIMINATION ET LE CONTRÔLE DES ODEURS
Abstract
(EN)
This invention relates to modified high surface area materials, such as nanoparticles that are coated with metal ions, and articles treated with the modified high surface area materials. The modified nanoparticles have active sites that bind various gases and/or odorous compounds, thereby removing these compounds from a medium such as air or water. Metal ions are adsorbed onto the surface of the nanoparticle and bound strongly to the surface. By selection of the metal ion, specific gaseous compounds and/or odorous compounds can be targeted and removed efficiently and effectively from both aqueous phase and from the air. The modified nanoparticles are applied to nonwoven webs to provide odor removing articles for industrial and consumer use in refrigerators and trash containers.
(FR)
La présente invention se rapporte à des matériaux modifiés à surface de contact élevée, tels des nano-particules recouvertes d’ions métalliques, et des articles traités avec les matériaux à modifiés surface de contact élevée. Les nano-particules modifiées ont des sites actifs qui lient divers gaz et/ou composés odorants, éliminant ainsi ces composés d’un milieu tel que l’air ou l’eau. Les ions métalliques sont adsorbés sur la surface de la nano-particule et fortement liés à la surface. Par sélection de l’ion métallique, des composés gazeux et/ou des composés odorants spécifiques peuvent être ciblés et éliminés de façon efficace et efficiente tant de la phase aqueuse que de l’air. Les nano-particules modifiées sont appliquées à des toiles non tissées pour fournir des articles éliminant les odeurs pour un usage industriel et domestique dans des réfrigérateurs et des récipients contenant des détritus.
