It was found in the literature that the tests made with ZVI in situ, especially for groundwater remediation, were performed using ZVI and nano zero-valent iron (nZVI) as well. Particles usually are used like a "trench-and-fill” installation. In this arrangement, ZVI or nZVI is disposed in the contaminated areas, applied alone or mixed with other materials. The aim of the current work is to evaluate the use of nZVI, which is synthesized in laboratory, for copper ion removal in aqueous solution. The present study will serve like a base focusing, in a future stage, on the use of nZVI on groundwater remediation. For this purpose, commercial ZVI particles were also tested in order to compare the removal behavior. During this study, a relation between the solution characteristic (pH, ion concentration) and the surface purity of the iron particles was found. This relation generally is not reported in the literature. Finally, the copper removal was satisfactory with ZVI and nZVI.
