METALLIC ION EXTRACTING REAGENT AND EXTRACTING METHOD

METALLIC ION EXTRACTING REAGENT AND EXTRACTING METHOD

PURPOSE:To separate ions of Cu, Ag, Au, a Pt group metal or Hg contained in an aqueous soln. from other various metallic ions by extraction at a high extraction rate by bringing the soln. into contact with a slightly water-soluble phase contg. chlorobutenyl-tertiary-amine in an acidic range. CONSTIT...

Zusammenfassung:PURPOSE:To separate ions of Cu, Ag, Au, a Pt group metal or Hg contained in an aqueous soln. from other various metallic ions by extraction at a high extraction rate by bringing the soln. into contact with a slightly water-soluble phase contg. chlorobutenyl-tertiary-amine in an acidic range. CONSTITUTION:An aqueous soln. contg. ions of Cu, Ag, Au or a Pt group metal and/or Hg is brought into contact with a slightly water-soluble phase contg. chlorobutenylamine at 2-6pH to separate said ions from other various metallic ions by extraction. The concn. of ions of Cu or the like in the aqueous soln. can be reduced to
