T1 - Testing the Suitability of Zerovalent Iron Materials for Reactive Walls Y1 - 2004 VL - 2 IS - 1 SP - 71 EP - 76 JF - Environmental Chemistry DO - 10.1071/EN04014 DO - 10.23689/fidgeo-835 N2 - Zerovalent iron (ZVI) has been proposed as reactive material in permeable in situ walls for contaminated groundwater. An economically feasible ZVI-based reactive wall requires cheap but efficient iron materials. From an uranium treatability study and results of iron dissolution in 0.002 M EDTA by five selected ZVI materials, it is shown that current research and field implementation is not based on a rational selection of application-specific iron metal sources. An experimental procedure is proposed which could enable a better material characterization. This procedure consists of mixing ZVI materials and reactive additives, including contaminant releasing materials (CRMs), in long-term batch experiments and characterizing the contaminant concentration over the time.
