Abstract
Description
本発明に係る希土類抽出剤は、ジケトンと中性抽出剤とを含有する。
上記の希土類抽出剤を用いて希土類を抽出するには、希土類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希土類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、有機相に希土類イオンを選択的に抽出することができる。
[実施例]
スカンジウム(Sc)、ネオジム(Nd)、ユーロピウム(Eu)、ディスプロシウム(Dy)、イットリウム(Y)、ランタン(La)をそれぞれ30mg/l含み、pHを0.1から2.6の範囲内で一定の値に調整した13種類の硫酸水溶液20mlを、13種類の硫酸水溶液のそれぞれについて実施例に係る希土類抽出剤20mlと混合し、回転数650rpmで20分間撹拌した。このとき、硫酸水溶液中のpHを混合前と同じ値に維持するため、1mol/lの水酸化ナトリウム水溶液を適宜添加した。その後、混合溶液の水相と有機相とを分液漏斗で分離し、抽出残液(水相)に対して、誘導プラズマ発光分光分析装置(ICP−AES)を用いた元素分析を行うことによって、各種希土類の水相から有機相への抽出率を求めた。pHと希土類の抽出率との関係を表2及び図1に示す。
硫酸水溶液のpHを1.5から4.5の範囲内で一定の値に調整したこと、及び希土類抽出剤として比較例に係る希土類抽出剤を用いたこと以外は、実施例と同じ手法にて各種希土類の水相から有機相への抽出率を求めた。pHと希土類の抽出率との関係を表2及び図2に示す。
