）。For this reason, methods of adding a tin compound, adding L-ascorbic acid, etc. have been devised as means for preventing precipitation (see Japanese Patent Publication No. 58-156539).
しかし前者の方法は毒性を有し、後者の方法は高価であ
るという不都合がある。However, the former method is toxic and the latter method is expensive.
そこで本発明は無害で、安価な沈澱防止手段を得ること
を目的として案出されたものである。Therefore, the present invention was devised for the purpose of providing a harmless and inexpensive means for preventing precipitation.

Ｉ）に対し２０〜１００重量％の酒石酸またはクエン酸
を加えることを特徴とする鉄（Ｗイオン水溶液の安定化
方法である。Means and agents for solving the problems, that is, the present invention provides iron (II) ions in an aqueous solution of iron (II).
This is a method for stabilizing an aqueous iron (W) ion solution, which is characterized by adding 20 to 100% by weight of tartaric acid or citric acid to I).
ここで用いる鉄（ＩＩ）イオン水溶液は、硫酸第一鉄、
塩化第一鉄、硝酸第−鉄等の水溶液であり。The iron(II) ion aqueous solution used here is ferrous sulfate,
It is an aqueous solution of ferrous chloride, ferrous nitrate, etc.
酒石酸とクエン酸は通常これらの１のみを選択して用い
るが、両者を混合して用いてもよい。Usually, only one of tartaric acid and citric acid is selected and used, but a mixture of both may be used.
酒石酸またはクエン酸がいかなる作用をして鉄（ＩＩ）

に好ましくは４０〜６０ｆｉ量チとすると優れた安定化
作用が得られる。What effect does tartaric acid or citric acid have on iron(II)?
Although it is unclear whether ion stabilization is possible, experiments have shown that tartaric acid or citric acid in the above ratio has a good stabilizing effect. An excellent stabilizing effect can be obtained when the amount is 40 to 60 fi.

い。Tartaric acid and citric acid have no deodorizing effect, and iron (I)
I) Deodorizing action of ions (no effect on the other two).
実施例 以下本発明の実施例について述べる。Example Examples of the present invention will be described below.
硫酸第一鉄（ＦｅｇＯ＜ ・６ＴＴｚＯ） １１０ ｇ

ある。Note that both of these solutions are deodorant stock solutions, and the
It is diluted 0 to 200 times and used as a deodorizer, and can be used indoors.
71 or as a soaking device for paper or the like.
これらの液をそれぞれビーカー１：入れ、室内に放置し

ろから沈澱が始った。When each of these solutions was placed in a beaker 1 and left in a room, they were both blue-green and transparent at first, and the solution containing tartaric acid turned blue after about 20 days, and the solution containing citric acid after about 22 days (it turned a dark brown color, Precipitation started around 1:25 days later.
比較のため、硫酸第一鉄のみを上記と同濃度に水溶し、
同様にビーカー（：入れて放置したところ、はじめに青
緑色であったものが、７日後ごろに褐色となり、１４日
後ごろに沈澱が始った。For comparison, only ferrous sulfate was dissolved in water at the same concentration as above,
Similarly, when it was placed in a beaker and left to stand, it was blue-green at first, but after about 7 days it turned brown, and after about 14 days, precipitation started.
以上から明らかなように、本発明によれば、鉄（ｒＤイ
オン水溶液の保存性を２〜３倍に延長することができる
。As is clear from the above, according to the present invention, the storage life of the iron (rD ion aqueous solution) can be extended by two to three times.
発明の効果
