Abstract
The favorable distribution equilibrium of the complex of Pd(II)-5-Cl-PADAB between the two phases of PEG2000-(NH4)2SO4-H2O extraction system was investigated. The extraction efficiency (%E), distribution coefficient and concentration factors are studied. Spectrophotometric characteristics of the complex in such a system are stable. This method was used to determine micro-amounts of palladium(II) in secondary alloys of Ni. This method of extraction overcomes many disadvantages of methods using usual organic reagents as solvents. It is a convenient, rapid, economical way.
