Metallic iron for environmental remediation: learning from electrocoagulation.
The interpretation of processes yielding aqueous contaminant removal in the presence of elemental iron (e.g. in Fe(0)/H(2)O systems) is subject to numerous complications. Reductive transformations by Fe(0) and its primary corrosion products (Fe(II) and H/H(2)) as well as adsorption onto and co-precipitation with secondary and tertiary iron corrosion products (iron hydroxides, oxyhydroxides, and...
متن کاملNanoscale Metallic Iron for Environmental Remediation: Prospects and Limitations
The amendment of the subsurface with nanoscale metallic iron particles (nano-Fe(0)) has been discussed in the literature as an efficient in situ technology for groundwater remediation. However, the introduction of this technology was controversial and its efficiency has never been univocally established. This unsatisfying situation has motivated this communication whose objective was a comprehe...
متن کاملCarbon-stabilized iron nanoparticles for environmental remediation.
Ferromagnetic carbon-coated Fe nanoparticles (core size of 15 nm, saturated magnetization of Ms=218 emu g(-1) and coercivity of Hc=62 Oe), fabricated at a mild temperature, demonstrate a strong ability to effectively remove more than 95 wt% of Cr(VI) in waste water via carbon shell physical adsorption, which is much higher than the commercially available Fe NPs.
متن کاملTesting the suitability of metallic iron for environmental remediation: Discoloration of methylene blue in column studies
A new method to correlate intrinsic reactivity and treatability efficiency of metallic iron (Fe) was evaluated. A 2.0 mg L methylene blue (MB) solution was used in gravity fed column experiments. The intrinsic reactivity of nine Fe materials (ten samples) was characterized using the EDTA test. Three commercial Fe materials ZVI1 (0.40 0.80 mm), ZVI9 (0.50 mm) and ZVI10 (0.45 0.55 mm) were tested...
متن کاملThe Suitability of Metallic Iron for Environmental Remediation: Back to The Origin
Aqueous contaminant removal in the presence of metallic iron is often regarded as a reductive transformation mediated by the Fe surface. However, successful removal of theoretically non-reducible contaminants has been largely reported. This paper presents a rebuttal of the concept of contaminant reductive transformation. It is argued through a careful examination of the evolution of the volume ...
