    Graphical Abstract
    • Abstract
  • A novel extraction system using KAu(CN) 2 CTMAB as aqueous phase and 30 % TBP dodecane as organic phase is studied by 198 Au radioactive tracer and FT IR spectroscopy. The results show that the organic phase separates into two phases, when the gold concentration is bigger than 20 g/L. From the analysis of FT IR it is seen that the most of gold is in the lower organic phase.
