Abstract
The synergistic extraction mechanism of uranyl sulfate by a binary extraction system HBHEHP + TBPO has been investigated. The condition of the aqueous phase is fixed, with a concentration of sulfate 0.500M and pH=2.00. The composition of synergistically extracted complex is UO2(HA2)·A·TBPO and the binary synergistic extraction equilibrium constant is determined to be
