Description
また、分離されたヒ素などの有害物も容易に回収できることから、ヒ素等を無害化することも可能であるという有利な効果を奏する。
本発明は、ヒ素、アンチモン、セレンを少なくとも一種含有するIII−V族化合物半導体などの被処理物に希土類金属化合物を含有する吸着剤を使用して、前記の有害な元素を分離し、ガリウム、インジウム、アルミニウムを回収するものである。「ヒ素、アンチモン、セレンからなる群から選択される少なくとも一種の元素を含有するIII-V族化合物半導体又は当該半導体材料」としては、前記ヒ素、アンチモン、セレンを含有している限り、特に限定されるものではない。本発明においては、ヒ素等を安全に処理しつつ希少金属を回収する方法を提供するものだからである。
図1−(1)、(2)は、上記した酸化燃焼法の後に、吸着剤を用いた選択吸着・分離工程を経て、ガリウム、インジウムを回収する一方、吸着したヒ素を無害化工程にて有機金属化合物へ合成する。
容量1.5mLのエッペンドルフチューブに、超純水1mL、表1に示す所定濃度のガリウム、ヒ素、インジウムを含む水溶液(原子吸光用標準液、1000mg/L)、および、乳鉢ですりつぶした吸着剤(日本板硝子社製アドセラ;珪藻土と希土類金属化合物を混合して焼成造粒したもの)を100mg入れた。これを30℃の恒温槽中で攪拌して、1時間、14時間、24時間、95時間後にそれぞれ30μLをサンプリングして超純水で3mLに希釈して、金属濃度をICP−MS法により分析した。吸着試験中の金属イオン濃度の経時変化を表2、表3および図2に示す。
次に、メチルコバラミンを用いてヒ素をメチル化することによる有機金属化合物を合成(無害化)について説明する。[化1]にメチルコバラミンの構造と、ヒ素無害化の反応過程を示す。

- ガリウム、インジウム、アルミニウムからなる群から選択される少なくとも一種の金属を回収する工程によって生じた、有害化合物中に存在するヒ素、アンチモン、又はセレンを、前記吸着剤を使用して選択的に吸着する工程を含む請求項1記載の方法。
- 前記ガリウム、インジウム、アルミニウムからなる群から選択される少なくとも一種の金属を回収する方法又は工程が、酸化燃焼法、真空加熱分解法、イオン交換樹脂を用いた分離精製法、中和沈殿法からなる群から選択される少なくとも一種の方法によるものである請求項1又は2項に記載の方法。
- 前記ヒ素、アンチモン、セレンからなる群から選択される少なくとも一種の元素を含有するIII−V族化合物半導体又は当該半導体材料が、半導体の製造、加工工程において発生する結晶屑、ウェハー屑、粉状の廃メタル、研磨廃液、スラッジ、スクラップ、エッチング廃液からなる群から選択される少なくとも一種を由来とするものである請求項1〜3項のいずれか1項に記載の方法。
- 前記希土類金属化合物が、セリウム,サマリウム,ネオジム,ガドリニウム,ランタン,イットリウムからなる群から選択される少なくとも1種の酸化物,水和物又は水酸化物である請求項1〜4項のいずれか1項に記載の方法。
