Abstract The synergistic extractions of uranium(VI) from hydrochloric acid solution and sulfuric acid solution with 1-phenyl-3-methyl-4-(2′-chlorobenzoyl)-pyrazolone-5 (PMCBP) together with the neutral extractants: tributyl phosphate(TBP), di-octyl sulfoxide(DOSO) and trioctylphosphine oxide(TOPO) in chloroform have been investigated. A high synergistic extraction effect was found. The formulas of the extracted species have been shown to be UO2A2B (where A=PMCBP, B=neutral extractant). The synergistic extraction power increases as follows: PMCBP-TOPO〉PMCBP-DOSO〉PMCBP-TBP. The equilibrium constants have been calculated. Models for the extraction mechanism are also discussed.
