The extraction equilibrium of leucine with di-(2-ethylhexyl) phosphoric acid (D2EHPA) dissolved in n-heptane,n-octane and kerosene respectively was studied in neutral condition.The values of extraction equilibrium constant K_ex and other thermodynamical data were obtained.The results show that one leucine molecule is extracted by complexing with two dimeric D2EHPA molecules,and the solvents do not affect the equilibrium in the conditions of the experiments.
