铁纳米粒子的沉积和剥离观察到从水溶液中的Fe 2+在pH 3的不锈钢电极在聚焦微波活化的存在下。研究了Fe ~（2+）浓度和微波功率对微波吸收的影响。结果表明，所得的铁纳米颗粒存款（i）给出了明确的阳极剥离响应，（ii）容易释放到溶液相，和（iii）是高度反应性的氯化烃，如三氯乙酸。增加的质量传输和局部微波加热的组合效应改善了污染物降解处理。
Iron nanoparticle deposition and stripping are observed from aqueous Fe2 +solution at pH 3 on stainless electrodes in the presence of focused microwave activation. The effects of Fe2 +concentration and microwave power are evaluated. It is shown that the resulting iron nanoparticle deposit (i) gives well-defined anodic stripping responses, (ii) is readily released into the solution phase, and (iii) is highly reactive towards chlorinated hydrocarbons such as trichloroacetate. The combined effects of increased mass transport and localized microwave heating improve pollutant degradation treatments.
