More Information
Summary:The present invention relates to novel compositions such as cysteine adsorbed on solid support media and trimercaptotriazine bound to silica gel, which are useful for the removal of heavy metals such as palladium form organic phases. The present invention also relates to methods of removing heavy metals by using these compositions. L'invention concerne de nouvelles compositions, par exemple la cystéine adsorbée sur un milieu de support solide et la trimercaptotriazine liée à un gel de silice, que l'on utilise pour évacuer des métaux lourds tels que le palladium des phases organiques. L'invention concerne en outre des procédés permettant d'évacuer des métaux lourds au moyen de ces compositions.
