ンが存在すると、３価の鉄イオンが抽出され、この鉄イ
オンに起因する不具合が生じるとされている。According to this method, diisodecylphosphoric acid (DIDPA) is used as one of the solvents in the solvent extraction step. At this time, if trivalent iron ions are present in the waste liquid to be treated, the trivalent iron ions are extracted, and problems caused by these iron ions are said to occur.

を添加して３価イオンを２価イオンにする方法等をとっ
ている。In order to solve this problem, conventional technology has adopted methods such as adding a solvent to lower the concentration of iron ions in the solvent, or adding a new reducing agent to convert trivalent ions to divalent ions. .

る廃棄物の増大という問題がある。However, in the former method, trivalent iron ions are not back-extracted in the back-extraction step, so they accumulate in the solvent, increasing the amount of solvent used.On the other hand, in the latter method, iron as divalent ions is not extracted. Since it is stable and easily susceptible to air oxidation, there is a problem in that a large amount of reducing agent is used, and the amount of waste increases due to the use of a new reducing agent.

の目的は果たされる。Titanium antimonate Tin antimonate The present invention efficiently removes iron from a solution with a pH of less than 7 in which two or more metals containing rare earth elements and iron are dissolved. Specifically, iron and Sc, Y, La are dissolved. "Iso)-B Handbook" for rare earth elements such as
Iron can be removed from a solution in which elements of group 3 A of the periodic table are dissolved, as described in the back spread of February 20th, published by Maruzen Co., Ltd., edited by Japan Isotope Association. In addition, for example, in the case of tin antimonate, iron and elements other than the Group 3 A elements mentioned above, such as Sr and Cs, which tend to be mixed in this type of liquid, are separated and removed along with iron. However, in the present invention, the purpose of separating iron is generally achieved regardless of whether such elements are mixed in with either the iron or the Group 3 A element that is to be separated from each other.
