Application of nanoscale zero valent iron (NZVI) for groundwater remediation in Europe [PDF]

Environmental Science and Pollution Research, 2011
Nanoscale zero valent iron (NZVI) is emerging as a new option for the treatment of contaminated soil and groundwater targeting mainly chlorinated organic contaminants (e.g., solvents, pesticides) and inorganic anions or metals. The purpose of this article is to give a short overview of the practical experience with NZVI applications in Europe and to ...
