Abstract
Selon un procédé utile pour rendre inoffensive la serpentine fibreuse, on humidifie les fibres d'amiante avec une solution aqueuse contenant entre 1 et 25 % en poids d'un faible acide organique, tel que l'acide trifluoroacétique. Facultativement, la solution aqueuse contient en outre entre 1 et 10 % en poids d'une source d'ions fluorure, telle que le fluorure d'ammonium. La faible solution acide hydrolyse les unités d'oxyde de magnésium dans l'amiante alors que les ions de fluorure attaquent les couches intercalées de silice dans la structure cristalline de l'amiante, détruisant la nature fibreuse de l'amiante.
