Title (EN) A SORBENT AND A FILTER
(FR) SORBANT ET FILTRE
Abstract:
(EN) A sorbent for capture of formaldehyde, comprising a hydrophilic amorphous precipitated silica material having a BET surface area of at least 200 m2/g, and an organic compound in the form of polyethylenimine (PE I) bound to a surface of the amorphous precipitated silica material.
(FR) L'invention concerne un sorbant pour la capture de formaldéhyde, comprenant un matériau de silice précipitée amorphe hydrophile ayant une surface BET d'au moins 200 m2/g, et un composé organique sous la forme de polyéthylènimine (PE I) lié à une surface du matériau de silice précipitée amorphe.
