摘要

Zero-valent iron (ZVI) permeable reactive barriers (PRBs) as well as direct application of nanoand/or microscale ZVI emulsions (NZVIs) by injection are effective in situ technologies for remediating groundwater plumes or source zones, respectively that are contaminated by chlorinated volatile organic compounds (cVOCs) or certain heavy metals. However, ZVI or NZVI types used for these purposes so far have been produced chiefly for entirely different industrial applications rather than application for groundwater remediation, i.e., they do not represent tailored reagents regarding their application to remediating contaminated sites. This contribution describes investigations and first results of a study performed during the second operational term of the German research and development (R&D) PRB cluster “RUBIN” between 2006 and 2010 (Birke et al., 2004; Birke et al., 2005; RUBIN, 2010), to address this issue in order to achieve an improved quality assurance regarding proper practical field scale implementations of different ZVI and NZVI brands and production charges.
