摘要：
The mechanism and characteristics about synergistic extraction of Nd3+ and Sm3+ by D2EHPA and HEHEHP from sulfuric acid medium were studied through the methods of slope, constant molecule and saturation extraction. The extraction equilibrium constants, enthalpy change and entropy change of the reaction were also calculated. The results show that the compositions of the extracted compound are identified as Nd&middot(HA2)2&middotHL2 and Sm&middot(HA2)2&middotHL2, the synergistic extractive effects are found, the extraction is an exothermic process. Consequently, the extraction and separation effect for rare earth can be improved with synergistic mixture of D2EHPA and HEHEHP.
