(4) 前記水溶液中のノニオン系界面活性剤の濃度が0.5〜1.0%である、(3)に記載の浄化方法。
本発明の汚染土壌中の有機塩素化合物の抽出方法は、有機塩素化合物で汚染された土壌に、ノニオン系界面活性剤とα−シクロデキストリンを含む水溶液を混合し、該水溶液に土壌中の有機塩素化合物を移行させることを特徴とする。
上記のとおり、本発明の抽出方法は汚染土壌から効率よく有機塩素化合物を抽出除去できるので土壌の浄化方法にも有効に利用することができる。
(a) 有機塩素化合物で汚染された土壌に、ノニオン系界面活性剤とα−シクロデキストリンを含む水溶液を混合し、該水溶液に土壌中の有機塩素化合物を移行させる工程(抽出工程)
(b) 有機塩素化合物を含む水溶液を土壌と固液分離後、電気分解する工程(脱塩素化工程)
(c) 固液分離後の土壌を脱水処理して回収する工程(再生工程)
蒸留水にノニオン系界面活性剤(ポリオキシエチレンアルキルエーテル:エマルゲン1108(花王社製))とα-シクロデキストリンを添加して洗浄液を作製した。まず、蒸留水にノニオン系界面活性剤の濃度が0、0.1、0.5、1.0%となるように添加し、このノニオン系界面活性剤濃度の異なる蒸留水にそれぞれα−シクロデキストリンを0.2%となるように添加した(試験ケースNo.1〜4)。
Claims (2)
- PCBで汚染された土壌に、ノニオン系界面活性剤とα-シクロデキストリンを含む水溶液を混合し、該水溶液に土壌中のPCBを移行させることを特徴とする、汚染土壌中のPCBの抽出方法であって、前記水溶液中のノニオン系界面活性剤の濃度が0.5〜1.0%、α-シクロデキストリンの濃度が0.1〜0.3%である、上記抽出方法。
- 下記の工程を含む、PCBで汚染された土壌の浄化方法。
(a) PCBで汚染された土壌に、ノニオン系界面活性剤とα-シクロデキストリンを含む水溶液を混合し、該水溶液に土壌中のPCBを移行させる工程であって、前記水溶液中のノニオン系界面活性剤の濃度が0.5〜1.0%、α-シクロデキストリンの濃度が0.1〜0.3%である工程
(b) PCBを含む水溶液を土壌と固液分離後、電気分解する工程
(c) 固液分離後の土壌を脱水処理して回収する工程
