しても安定化効果が充分でないという欠点を有する。(Prior art) Divalent iron compounds such as ferrous sulfate and ferrous chloride are used as raw materials for various purposes such as deodorizers, iron black, mordants, freeze treatment agents, medicines, bookbinding, and red iron. ing. but,
These aqueous solutions are easily oxidized by fluorine in the air and dissolved oxygen, and the problem is that they form yellow precipitates and are consumed within a short period of time.
To deal with this problem, methods of adding amine compounds such as alkanolamines or reducing agents such as tin chloride to divalent iron compound aqueous solutions have been proposed, but even when added in relatively large amounts, there is no stabilizing effect. It has the disadvantage of not being sufficient.

水溶液に所定のオΦシカルゴン酸を所定量添加し溶解し
た。各水溶液１００ｔ１１ｔを１００−ビーカーに入れ
、ガラス板をのせて放置し、水溶液の色並びに沈殿の生
成の時期を観察し九・結果を第１表に示す。Example 1 A predetermined amount of oscargonic acid was added and dissolved in an aqueous solution of ferrous sulfate whose iron content was adjusted to a concentration of 5 oil/l. 100t of each aqueous solution was placed in a 100mm beaker, a glass plate was placed on top of the beaker, and the solution was left to stand, and the color of the aqueous solution and the timing of the formation of precipitate were observed.9.The results are shown in Table 1.
第１表の結果から、無添加の場合（実験番号１）には短
