  • METHOD FOR THE CATALYZED REDUCTION OF HALOGEN OXYANIONS IN AQUEOUS SOLUTIONS
    Publication number: 20160347634
    Abstract: A method for removing halogen oxyanions, in particular chlorine and bromine, by hydrogenation reduction catalysed with supported catalysts based on rhenium and noble metals of subgroup VIII of the Periodic Table of the Elements is herein disclosed. The combination of the noble metals with rhenium has proved to considerably increase the catalytic efficiency of such metals.
