The invention relates to a method for the treatment of a composition containing inorganic silanes and at least one foreign metal and/or a compound containing a foreign metal, wherein the composition is brought in contact with at least one adsorption agent, and for obtaining the composition, in which the content of foreign metal and/or of a compound containing a foreign metal is reduced, and to a corresponding composition having a reduced foreign metal content, and further to the use of organic resins, activated carbons, silicates, and/or zeolites for the reduction of foreign metals and/or compounds containing foreign metals in compositions of inorganic silanes.
L'invention concerne un procédé utilisé pour traiter une composition contenant des silanes inorganiques et au moins un métal exogène et/ou un composé contenant un métal exogène. Ladite composition est mise en contact avec un agent adsorbant et la teneur en métal exogène et/ou en composé contenant le métal exogène de la composition ainsi obtenu est ensuite réduite. L'invention concerne également une composition correspondante à teneur en métal exogène réduite, ainsi que l'utilisation de résines organiques, de charbons actifs, de silicates et/ou de zéolites pour réduire la proportion de métaux exogènes et/ou de composés contenant du métal exogène dans des compositions de silanes inorganiques.
