Description
本発明におけるコバルト抽出剤は、アミン系抽出剤とオキシム系抽出剤との混合物である。アミン系抽出剤は官能基が1級アミンであれば、どのような構造のものでも構わない。具体的には、ターシャルブチルアミンやモノオクチルアミンのほか、PRIMENE(登録商標)JM−T型(ダウケミカル社製)等が挙げられる。これらの1級アミンは単独で用いてもよいし、2種類以上を混合して用いてもよい。
上記のコバルト抽出剤を用いてコバルトを抽出するには、コバルトイオンを含む酸性水溶液を調整し、この酸性水溶液と上記コバルト抽出剤とを混合して撹拌する。その後、混合溶液の水相と有機相とを分液漏斗で分離することで、有機相にコバルトイオンを選択的に抽出することができる。
[ターシャルブチルアミン含有コバルト抽出剤の調製]
アミン系抽出剤としてターシャルブチルアミンを使用し、オキシム系抽出剤として上記LIX63を使用した。ターシャルブチルアミン及びLIX63のいずれもが0.5mol/lとなるように各々の抽出剤をトルエンに溶解させることで、本発明に係るターシャルブチルアミン含有コバルト抽出剤(以下、「コバルト抽出剤A」という。)を得た。
[モノオクチルアミン含有コバルト抽出剤の調製]
アミン系抽出剤としてモノオクチルアミンを使用し、オキシム系抽出剤として上記LIX63を使用した。モノオクチルアミン及びLIX63のいずれもが0.5mol/lとなるように各々の抽出剤をトルエンに溶解させることで、本発明に係るモノオクチルアミン含有コバルト抽出剤(以下、「コバルト抽出剤B」という。)を得た。
Claims (5)
- ターシャルブチルアミン及び/又はオクチルアミンを含有するアミン系抽出剤と、オキシム系抽出剤とを含有するコバルト抽出剤。
- 1級アミン系抽出剤とオキシム系抽出剤とを含有し、
前記1級アミン系抽出剤とオキシム系抽出剤とのモル比が20:80〜80:20である、コバルト抽出剤。 - マンガン及びコバルトを含有する酸性溶液のpHを4.0以上6.0以下の範囲に調整した後、前記酸性溶液を、アミン系抽出剤とオキシム系抽出剤とを含有するコバルト抽出剤による溶媒抽出に付し、前記酸性溶液から前記コバルトを抽出するコバルト抽出方法。
- 前記アミン系抽出剤は1級アミン系抽出剤である、請求項3に記載のコバルト抽出方法。
- 前記1級アミン系抽出剤はターシャルブチルアミン及び/又はオクチルアミンを含有する、請求項3又は4に記載のコバルト抽出方法。
