| titleOfInvention | METHOD FOR PRODUCING NITROGEN AND SULFUR ADSORBENTS |
| abstract | The invention relates to a process for the preparation of bifunctional nitrogen- and sulfur-containing adsorbents for the binding of heavy metals, especially silver and mercury. The object of the invention was to develop a process for the preparation of such adsorbents with improved properties based on vinylaromatic polymers. It has now been found that it is possible to produce corresponding adsorbents by substituting the amine component of a gel-type or macroporous styrene-divinylbenzene copolymer substituted by at least one alkyl group 2 or starting from such a halogen-substituted alkylamine group on the polymer and using sulfur-containing reagents , such as alkali metal sulfides, alkali hydrogen sulfides, rhodanides, thioureas or Thiosemicarbaziden. The combination of metal-affinity and anion-exchange groups provides such products with the potential for incorporation of cationic and anionic metal species, and thus a wider range of applications. |
