Synergistic reactive extraction of platinum (IV) from aqueous solution was conducted using an organic phase consisting of tributylphosphate (TBP) and bis (2,4,4-trimethylpentyl monothiophosphinic acid (Cyanex 302) in kerosene. Influence of different type of single extractants, mixtures and their com...
