The extraction ability of palladium( Ⅱ ) from acidic media with cyclic sulfoxide derivatives-α-Dodecyl-tetrahydrothiophene 1-Oxide (DTMSO), α-octyl-tetrahydrothiophene 1-Oxide (OTMSO) and α-butyl-tetrahydro-thiophene-1-Oxide (BTMSO) was investigated. The extracting efficiency of cyclic sulfoxide derivatives decreased with the increasing of acidity in the lower acidity, and the efficiency became stable with the change of acidity in the higher acidity. The extraction reaction of palladium( Ⅱ )with DTMSO is exothermic, and extraction reaction of pal-ladium( Ⅱ ) is endothermic when OTMSO or BTMSO were used as extracting reagents. The coordination number was studied by slope method. The results indicate that coordination number is 2, and the composition of complex is Pd is coordinated with both oxygen and sulfur atom in S=O group in sulfoxide derivatives.
