The effect of phosphoric acid on extraction separation of rare earth(Ⅲ)and iron(Ⅲ)from sulphuric acid solution by primary amine N₁₉₂₃ was investigated.The behavior of different primary amine and solvent or temperatures in dependence on the extraction seperation of rare earth(Ⅲ)was studied.The mechanism of iron(Ⅲ)extraction from phosphciic acid solution was proposed.The IR study was carried out for the organic phase.
