Abstract
The new favorable distribution equilibrium of the complex of Ru(III)-c hrome azurol S between the solid and liquid phases of Tween 80-(NH4)(2 )SO4-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 ar e stable. This method was used to determine microamounts of ruthenium( III) in secondary alloys of Ni. This method of extraction overcomes ma ny disadvantages of methods using usual organic reagents as solvents.
