A new spectrophotometric method for determining the extraction constant of quaternary complexes.
A new spectrophotometric method for determining the extraction constants of quaternary complexes is described. The method has been applied to a study of the distribution between water and toluene in the V(V)-salycylhydroxamic acid-nitrate-trioctyl methyl ammonium system, determining its conditional extraction constant in toluene for several pH values.
