Abstract
【解決手段】 ヒ素に汚染された水中のヒ素を除去するための除去剤であって、鉄粉の表面が鉄の水酸化物で被覆されている、ヒ素除去性能に優れると共に除去後の処理効率にも優れたヒ素除去剤である。この除去剤は、水に可溶性の鉄塩を含む水溶液中で鉄粉を撹拌し、該鉄粉の表面に鉄水酸化物を生成・付着させることによって得ることができる。
Description
1-1)塩化鉄を0.1モル/Lとなる様に蒸留水に溶解し、1Lの塩化鉄水溶液を調製する。該水溶液のpHは1であった。
上記実施例で用いたアトマイズ鉄粉(株式会社神戸製鋼所製の商品名「アトメル」;平均粒径65μm)をそのままで使用した。
2-1)塩化鉄を1モル/Lとなる様に蒸留水に溶解して1Lの塩化鉄水溶液を調製する。該水溶液のpHは0.5であった。
3-1)ヒ素含有被処理水のモデル液として、ヒ酸カリウム(KH2AsO4)をAs濃度で1mg/Lまたは10mg/Lを含む水溶液を準備する。
Claims (2)
- ヒ素に汚染された水中のヒ素を除去するための除去剤であって、鉄粉の表面が鉄の水酸化物で被覆されたものであることを特徴とする汚染水中のヒ素除去剤。
- 鉄粉を、水に可溶性の鉄塩を含む水溶液中で撹拌し、該鉄粉の表面に鉄水酸化物を生成・付着させることを特徴とするヒ素除去剤の製法。
