FIELD: production of selective sorbents. SUBSTANCE: method is carried out by sorption of multifunctional compound followed by its condensation with formaldehyde. Said sorption takes place on macroporous anionite, mentioned above condensation is carried out inside pores of said anionite. Soluble sulfides or hydrosulfides of metals of gaseous hydrogen sulfide are used as said multifunctional compound, anionite of polymerization or polycondensation type which contains groups of quaternary ammonium base and/or primary and secondary amino groups is used as mentioned above anionite. Thus prepared sorbent enables selective separate ions of mercury and silver of various aqueous mediums. EFFECT: improved efficiency. |
