Abstract

Using dodecane as diluent ,the extraction behavior of molybdenum(Ⅵ) with Bis-(2-ethylhexyl) phosphate from nitric acid solution is studied.Temperature has evident effect on distribution ratio of molybdenum(Ⅵ) .There is obvious heat effect in the extraction process .From 3 mol/L HNO3 solution ,molybdenum(Ⅵ) is extracted in the form of MoO2+2.The composition of the extraction complex is MoO2(NO3)2·2D2EHPA. The extraction equilibrium is given.
