Description
本発明は、ハロゲン化炭化水素で汚染された土壌、水又は地下水の浄化に適した鉄−ホウ素合金粉末又は鉄−ホウ素合金粉末組成物、並びに該粉末又は該粉末組成物の使用に関する。さらに、本発明は、ハロゲン化炭化水素で汚染された土壌、水又は地下水の浄化方法を提供する。市販のかなり微細なゼロ価鉄粉と比べて、本発明の新規材料がハロゲン化炭化水素の分解のための同程度の又はより高い活性を有することが示されている。
本発明は、上記の課題に対する解決策を提供し、ホウ素(B)と合金化したZVI粒子が、驚くべきことにハロゲン化/塩素化炭化水素で汚染された水及び土壌を分解する点で高い効率を示すという予想外の発見に基づいている。また、いわゆるナノサイズのスケールを上回り比較的粗い粒子サイズを有している、Bと合金化したZVIは、より微細なZVI及び/又はナノスケールのZVIと比べて、ハロゲン化/塩素化炭化水素で汚染された水及び土壌の分解のための同等の又はより高い活性を有することも示されている。
以下の例は、表1に記載の種々の材料の、いくつかのCAHの分解能力を示している。使用したCAHは、テトラクロロエチレン(PCE)、トリクロロエチレン(TC)、シス−ジクロロエチレン(cDCE)及び1,1,1トリクロロエタン(111−TCA)であった。
実施例1の汚染物質の分解の間、様々なZVI材料が部分的に消費されただけでなく、ZVI材料と嫌気性水との反応により水素が発生していた。このようにして、生成した水素の測定により、各ZVI材料の腐食速度を計算することができた。実施例1のいくつかのZVI材料の腐食速度と寿命を、以下の表7に示す。
ZVIの存在下での多数の汚染物質の脱塩素率を、擬一次反応速度式;C=C0*e−kt(Cは任意の時点における濃度、C0は初期濃度、kは一次崩壊定数[日−1]及びtは反応時間[日])を用いて計算した。半減期を、t1/2=ln2/k[日]として計算した。
