Chromium(III) has been reported to be non-extractable as an ion association complex with high molecular weight amines (1). This is probably due to the slowness with which the coordinated water molecules are replaced by negative ions. Stability constant data show that chromium(III) should form an anionic complex with thiocyanate which might be extractable as an ion association complex with high molecular weight amines (2). This study examines the extraction characteristics of such a system and attempts to separate other transition metal ions from chromium(III). EXPERIMENTAL Apparatus. A Tracerlab Model P-20D scintillation detector connected to a Model SC-71 scaler was used to count the gammaemitting isotopes in both the organic and the aqueous phases. An Eberbach water bath shaker was used for agitation of the samples.
