Abstract
The equilibrium and kinetics of the extraction of palladiura(II) ion with dioctyl sulfide (R-S) in chloroform have been studied at 25 C and an ionic strength of 1.0 M. The extracted species was found to be pdcl2 (R2S) and to have an extraction constant log Kex. =9.84 The observed rate expression for the extraction: -d[Pd]T/dt = k [Pd]T[R2S]o/[cl-], supports a mechanism in which the rate-determining step is the reaction of PdCl3(H2O) - with R2 S in the aqueous phase.Keywords
