The sorption of Eu(III) on Th4(PO4)4P2O7 was studied under ambient conditions using the batch technique. The effects of pH, the concentrations of Eu(III) on Th4(PO4)4P2O7 sorption were investigated. The sorption characteristics of sulfate, phosphate and fulvic acid (FA) on Th4(PO4)4P2O7 was explored in the presence Eu(III). The results indicated that sorption of Eu(III) on Th4(PO4)4P2O7 was strongly affected by pH and the concentrations of Eu(III). Eu(III) sorption onto Th4(PO4)4P2O7 was greatly enhanced in FA and phosphate media than in KNO3. The Langmuir, Freundlich and D–R model were used to simulate the sorption isotherms of Eu(III) at four different medium. FA sorption isotherm can be described by Langmuir model in presence and absence of Eu(III) in solution.
