Abstract: In this paper the extraction of palladium with bis (n-octylsulfide) ethane [C₈H₁₇S(CH₂)₂SC₈H₁₇) has been studied. The effect of concentration of hydrochloric acid and diluent has been discussed. It was shown that bis (n-octylsulfide) ethane is highly effective extractant of palladium from hydrochloric acid medium. Compostion of extracted complex was established by method of isomolar series and of saturation, Asmus's me -thod and chemical analysis of solid complex and found to be Pd: bis (n-octylsulfide) ethane = 1:1. Study on the nuclear magnetic resonance spectrum and infrared spectrum indicated that bis (n-octylsulfide) ethane is coordinated to palladium through sulphur to form five-membered neutral chelate complex.
