宙開発分野で注目されている。Potassium is a raw material for fertilizers, optical glass, and gunpowder, and in the future it will be important as a heat exchange medium for fast breeder reactors. Rubidium is used as a material for photoelectron tubes, but it is also attracting attention in the field of space exploration as a fuel for ion propulsion engines in the future.

成物として採取されている。Sylvite, carnallite, and langbeinite are known as potassium ore resources, but these ores are not produced in Japan. In Japan, potassium is extracted from seawater or concentrated seawater as a double salt, but it is difficult to call this an economical method because concentration requires a large amount of energy. In the case of rubidium, since there are no ores that contain rubidium as a main component, it is collected as a by-product.

カリウム及びルビジウムを含む希薄溶液から該アルカリ
金属を吸着回収するためには、次の要件を満たす吸着剤
を用いることが必要である。(Problems to be Solved by the Invention) In order to adsorb and recover the alkali metal from a dilute solution containing potassium and rubidium, it is necessary to use an adsorbent that satisfies the following requirements.

着剤であることが要求される。In other words, a dilute solution containing potassium and rubidium generally contains dissolved sodium ions, magnesium ions, etc., and in some cases contains large amounts of silica and calcium carbonate, so it may be affected by these coexisting elements. It is an adsorbent that can selectively adsorb potassium and rubidium, and since the concentration of potassium and rubidium in the solution is low, it has a high adsorption capacity and adsorption rate. The adsorbent is required to be stable in the dilute solution and to be inexpensive.
