Beschreibung
Zusammenfassung:	precious metal technology. SUBSTANCE: invention relates to the field of ion-exchange isolation of small amounts of metal ions from process solutions and can be employed in chemical industry, metallurgy, and electroplating. Solution is passed through sorbent containing inert material and absorbing layer: lead sulfide film 500-1500 nm thick. EFFECT: increased sorbent capacity (by at least one order of magnitude). 1 tbl, 25 ex
