By using Th‐234 as tracer, the synergistic effects in the extraction of thorium from aqueous solutions with mixtures of organic solvents were investigated for the system Th 4+ /β‐diketones/TBP/diluents. Four β‐diketones, i. e ., acetylacetone, benzoylacetone, dibenzoylmethane and trifluoroacetone, were used. Synergistic enhancements on the distribution ratios were observed in all cases except when acetylacetone was used as the chelating agent at the p H range of 2–3. Based on the experimental observations, a plausible mechanism for the synergistic effect has been suggested. The effect of diluent is also dicussed.
