    • When elemental iron is in the presence of chlorinated compounds (contaminants) a naturally occurring reaction takes place and the chlorinated compounds are reduced and form harmless compounds. The production of extremely small metal particles containing elemental iron or a mixture of elemental iron and a second metal is imperative to this method of treating contaminants and is the subject of the present invention. When the particle is made small enough a surfactant is not required for the particle to do its job. The elemental metal may be kept in an elemental state by keeping it in an oxygen-scavenging environment. This is achieved by either suspending the nanoscale metal in a carbohydrate solution or by injecting a carbohydrate solution in atomized form into the gas used to inject the metal into the subsurface soil. Additionally, the present invention is to a method of using elemental metal to reductively dehalogenate halogenated hydrocarbons, to reduce soluble metals and to treat metalloids in subsurface soil.
    • 当元素铁存在氯化化合物(污染物)时,发生天然存在的反应,并且氯化化合物被还原并形成无害化合物。 生产含有元素铁或元素铁和第二种金属的混合物的极小的金属颗粒对于这种处理污染物的方法是必不可少的,并且是本发明的主题。 当颗粒制得足够小时,颗粒不需要表面活性剂来完成其工作。 元素金属可以通过保持在氧气清除环境中而保持在元素状态。 这是通过将纳米级金属悬浮在碳水化合物溶液中或通过将雾化形式的碳水化合物溶液注入用于将金属注入地下土壤中的气体来实现的。 此外,本发明是一种使用元素金属来还原卤代卤代烃,减少可溶性金属和在地下土壤中处理准金属的方法。
