Description
5%シュウ酸溶液1.0Lに対しインジウム(In)を1.64g、スズ(Sn)を0.15gの割合で溶解し、インジウム濃度1.64g/L、スズ濃度0.15g/Lのシュウ酸溶液を作成し、これをエッチング廃液とした。
実施例1において、イオン交換樹脂をH形の強酸性陽イオン交換樹脂(SKN1、三菱化学(株)製)に変えた(シュウ酸処理は行わず)以外は、実施例1と同様にしてエッチング廃液の処理を行った。処理液のインジウム、スズ濃度変化を図1に示す。図1中、インジウムの濃度変化をB−1で示し、スズの濃度変化をB−2で示す。
Claims (1)
- インジウム含有被エッチング材を処理したシュウ酸エッチング廃液から溶解した金属成分を分離して高純度のシュウ酸水溶液を回収する方法であって、シュウ酸エッチング廃液と、強塩基性陰イオン交換樹脂をシュウ酸で接触処理することにより得られるシュウ酸形陰イオン交換樹脂とを接触処理させることを特徴とする高純度シュウ酸水溶液の回収方法。
