FIELD: chemistry.
SUBSTANCE: inert inorganic substrate is soaked with solution of lithium aluminium hydride in diethyl ether. Ether is removed by vacuuming and pyrolysis of lithium aluminium hydride, applied on substrate, is realised at temperature 100-500°C in vacuum.
EFFECT: obtaining sorbent, effective for purification of inert gases and reducing gases from admixtures of Lewis acids, hydrocarbons, oxygen or volatile oxides.
