这项拨款申请将支持对受污染地下水原位修复技术的潜在改进进行研究。零价铁(还原铁)纳米颗粒具有反应性,能够迅速消除地下水中常见的一些有毒和潜在致癌污染物,如三氯乙烯、铬和砷。这使得零价铁纳米颗粒成为污染场地地下水修复的极好反应物。此外,零价铁被转化为氧化铁,在土壤中无处不在,自然存在。
英文摘要
This grant application will support research investigating potential improvements to in situ remediation technologies for contaminated groundwater. Nanoparticles of zero valent iron (reduced iron) are reactive and are able to rapidly eliminate a number of toxic and potentially carcinogenic pollutants commonly encountered in groundwater, such as trichloroethylene, chromium and arsenic. This makes the nanoparticles of zero valent iron an excellent reactant for remediation of groundwater at contaminated sites. Furthermore, the zero valent iron is converted to iron oxides, which are ubiquitous in soil and naturally present.
