Synergistic extraction of Am(Ⅲ) and Eu(Ⅲ) is studied with terpyridine (Tpy) in combination with2-bromodecanoic acid (HA) in tert-butylbenzene (tbb). The distribution ratios of Am(Ⅲ) and Eu(Ⅲ) arestudied as a function of a number of parameters such as contact time, the acid concentration in aqueousphase, the concentration of Tpy and HA in the organic phase. The experimental results show that thevalues of distribution ratios of Am(Ⅲ) and Eu(Ⅲ) in Tpy/tbb is small, but after adding HA to Tpy/tbbsystem, the values of distribution ratios D(M), (M=Am(Ⅲ), Eu(Ⅲ)) increase fast. D(M) values increase
