Description
金属として金属鉄(平均粒子径が5.0μm程度の電解金属鉄粉:特級試薬、関東化学製)、金属酸化物として酸化鉄(平均粒子径が0.1μm程度のベルトライド(FeO1.447)粉末)を用い、これらを重量比で3対1、1対1、0.33対1で混合し、本発明の有機化合物分解材(試料A〜C)を得た。それぞれを実施例1〜3とする。
金属として実施例1で用いた金属鉄、金属酸化物として鉄含有廃硫酸を中和・酸化して得られた酸化鉄(平均粒子径が0.07μm程度のベルトライド(FeO1.39)粉末)を用い、これらを重量比で3対1、1対1、0.33対1、0.1対1で混合し、本発明の有機化合物分解材(試料D〜G)を得た。それぞれを実施例4〜7とする。
実施例1〜7で用いた電解金属鉄粉、実施例1〜3で用いたベルトライド粉、実施例4〜7で用いたベルトライド粉を、各々比較例とした。(試料H〜J)
実施例1〜3、比較例1、2で得られた試料A〜C、H、Iを、3ppmトリクロロエチレン水溶液に25g/リットルとなるように添加し、バイヤル瓶に密栓し24時間振盪撹拌して処理した。処理してから1日、7日経過後の水溶液に含まれるトリクロロエチレン濃度を、GC−MSヘッドスペース法にて測定した。また、処理後の水溶液の色を、目視で判定した。
蒸留水にγ‐BHCが1ppmの濃度になるように加えた試験液100ミリリットルを調製し、この試験液に実施例4〜7の試料D〜G、比較例1、3の試料H、Jを各々10g添加した後、バイヤル瓶に密栓し24時間振盪撹拌して処理した。また、試験液に試料を加えなかったものを、比較例4とした。次いで、試料全量を100ミリリットル分液漏斗に入れ、塩化メチレン10ミリリットルを加え、10分間混合した後、下層(塩化メチレン層)を採取し、この抽出液を自然濾過した。残った上層(水層)に、更に塩化メチレン10ミリリットルを加え、10分間混合した後、下層(塩化メチレン層)を採取し、この抽出液を自然濾過し、1回目の抽出液と合わせた。得られた抽出液に無水芒硝2gを加えて10分間水分を吸着させ、その後、自然濾過により無水芒硝を分離した。この抽出塩化メチレンに含まれるBHCの濃度を、GC−MSヘッドスペース法にて測定した。
