Abstract: PURPOSE: To obtain phosphoric acid having improved purity by bringing an aq. phase contg. the phosphoric acid into contact with a specific immiscible org. extractant in an aliphat. hydrocarbon diluent.  
     CONSTITUTION: The aq. phase contg. the phosphoric acid is supplied through a piping 1 into an extraction zone and is brought into contact with the aliphat. hydrocarbon diluent contg. the immiscible org. extractant consisting of a mixture composed of a weight ratio ≥1:2 of mono(2-ethylhexyl)orthophosphoric acid and di(2-ethylhexyl)orthophosphoric acid supplied through a piping 3, by which iron (III) is extracted. The aq. phase in which the iron-component is lowered is taken out of a piping 5. On the other hand, the org. phase having the high iron-component is supplied through a piping 4 to a stripping zone where the org. phase is brought into contact with the aq. phase contg. a stripping agent, such as ammonium bifluoride, supplied through a piping 6 to migrate the iron (III) to the aq. phase. The org. layer having the low ironcomponent is recirculated through a piping 8. The aq. phase having the high iron-component is sent to a separating zone 10 where the iron (III) is separated.
