Abstract

Matériau adsorbant constitué, en particulier, par un substrat de support sous forme de feuille incorporant des adsorbants en particules afin de filtrer des liquides, sous l'effet d'interactions entre gaz et solides ou entre liquides et solides, le contaminant, tel qu'un atome, un ion ou une molécule de gaz ou de liquide, adhérant ou étant sinon retenu par la particule solide d'adsorbant, ce qui enlève ledit contaminant du liquide filtré. On prépare un substrat de support perméable aux liquides contenant des fibres capables de résister à un contact prolongé avec un liquide à filtrer, on traite ce substrat afin d'y introduire des agents de fixation comprenant un liant et une substance filmogène, ainsi qu'un ou plusieurs matériaux absorbants en particules, la quantité d'agents de fixation, particulièrement, de substances filmogènes, suffisant à retenir ledit ou lesdits matériaux absorbants dans le substrat, ce qui évite pratiquement d'en rejeter l'adsorbant.
