Abstract
Description
本発明では、カルシウム、マグネシウム及びスカンジウムを含有する酸性溶液を特定のアミド誘導体が含浸されたスカンジウム回収樹脂に1時間以上接触させる。
アルキルアセトアミドを加え、求核置換反応によりグリシン又はN−アルキルグリシン誘導体の水素原子の一つを(N,N−ジ)アルキルアセトアミド基に置換する。これら2段階の反応によってグリシンアルキルアミド誘導体を合成できる。
樹脂は、多孔質樹脂であれば特に限定されるものでなく、アクリルエステルポリマー、スチレン系ポリマー等が挙げられる。本明細書において、多孔質とは、溶剤が浸入できる程度に細孔を有することをいう。多くの抽出剤を浸入できるようにするため、多孔質樹脂は比表面積の大きいものが好ましい。
本発明において、スカンジウム回収樹脂は、次のようにして得られる。まず、上記アミド誘導体をトルエン等の揮発しやすい溶剤に溶解させ、低粘性の液体とする。これに上記樹脂を浸した後、溶剤を留去させる。これらの工程を経ることでスカンジウム回収樹脂が得られる。
上記スカンジウム回収樹脂を用いたスカンジウムの回収は、次のようにして行われる。まず、上記スカンジウム回収樹脂にスカンジウムイオンを吸着させる。続いて、溶離液を用いて、スカンジウム回収樹脂に吸着したスカンジウムイオンを回収する。
[アミド誘導体の合成]
アミド又はアミド誘導体からなるスカンジウム抽出剤の一例として、上記一般式(I)
で表されるグリシンアミド誘導体、すなわち、2つの2−エチルヘキシル基を導入したN,N−ジ(2−エチルヘキシル)アセトアミド−2−グリシン(N,N−di(2−ethylhexyl)acetamic−2−glycine,以下「D2EHAG」という。)を合成した。
上記アミド誘導体30gを100mlのトルエンに溶解させ、アミド誘導体のトルエン希釈液を得た。この液にアクリルエステルポリマーの多孔質樹脂(製品名:アンバーライトXAD−7HP,Dow chemical社製)30gを添加し、樹脂中に抽出剤を含浸させた。その後、60℃に温度を保持しながら、減圧状態でトルエンを留去してD2EHAGを含浸させることで、スカンジウム回収樹脂(含浸樹脂)を得た。
スカンジウムを含有する酸性溶液は、公知の技術に従って作製したものを用いた。具体的には、ニッケル酸化鉱石を硫酸溶液と共に混合し、加圧装置に装入して240〜250℃に加熱し、浸出スラリーを得た。その後、浸出スラリーに消石灰を添加して中和し、次いで、中和後液に硫化剤を添加し、中和後液からニッケル、コバルト、亜鉛等を除いた。ニッケル等を除いた後の中和後液を酸性溶液とした。
Claims (3)
- 前記アミド誘導体がグリシンアミド誘導体、ヒスチジンアミド誘導体、リジンアミド誘導体及びアスパラギン酸アミド誘導体のいずれか1以上である、請求項1に記載のスカンジウム回収方法。
- 前記酸性溶液は、ニッケル酸化鉱石に硫酸を混合してニッケルを浸出した溶液である、請求項1又は2に記載のスカンジウム回収方法。
