摘要
In this work,the extraction behavior of TBMA employing benzene as a diluents for Yb（Ⅲ）was investigated.The effect of the concentrations of nitric acid,lithium nitrate and extractant and also the temperature on the extraction distribution ratio was studied.The complexe of TBMA with Yb（Ⅲ） was characterized by IR.The stoichiometries of extracted species was established to be Yb（NO3）3·3TBMA,and the enthalpy of the extraction was found to be -29.46 kJ·mol-1.
