Abstract: The interfacial properties of surface active agents, HDEHP, HEHEHP, TOPO, TBP.SDS.CTMAB.were investigated at 298 K.The interfacial adsorption parameters, Cmin, A1 and Langmuir's adsorption constant Kwere calculated respectively.The effect of additives on the interfacial tensions were discussed.The causes of the additives for the increase and/or decrease of extraction rate were also explained.

Key words: interfacial property, Surfactant, Bi(2-ethylhexyl) phosphate, 2-Ethylhexylphosphoric acid mono 2-ethylhexyl ester
