The present invention relates to a nanoscale zero-valent iron and a method for producing the nanoscale zero-valent iron, and more specifically, to a nanoscale zero-valent iron for treating soil and groundwater contaminants comprising dissimilar metals, and a method for producing the nanoscale zero-valent iron for treating soil and groundwater contaminants. One purpose of the present invention is to provide a nanoscale zero-valent iron comprising new dissimilar metals which is effective in the treatment of soil and water. Another purpose of the present invention is to provide a method for producing a nanoscale zero-valent iron comprising new dissimilar metals which is effective in the treatment of soil and water. The other purpose of the present invention is to provide a method for effectively treating contaminated soil and water using the method for producing the nanoscale zero-valent iron comprising the new dissimilar metals. An agent for treating soil and/or water according to the present invention comprises nanoscale zero-valent iron doped with bismuth, and exhibits a maximally threefold improved treatment efficiency compared to existing nZVI at aerobic/anaerobic conditions in the purification treatment of environmental pollutants such as RDX and others. 본 발명은 나노 영가철 및 그 제조 방법에 관한 것으로서, 보다 상세하게는 이종 금속을 포함하는 토양 및 지하수 오염물질 처리용 나노 영가철 및 그 제조 방법에 관한 것이다. 본 발명에 따른 토양 및/또는 수처리제는 비스무스로 도핑된 나노 영가철을 포함하며, RDX 등 환경오염물질의 정화처리에 있어 호기/혐기조건에서 기존의 nZVI에 비해 최대 3배가 향상된 처리효율을 나타낸다.
