SynopsisThe book examines the suitability of nanoscale zero-valent iron (ZVI) for degradation of agrochemicals for the purpose of developing a cost-effective treatment technology. It identifies by-products produced from the ZVI-mediated degradation process of particular contaminants, and clarifies the reaction mechanism by which ZVI degrades a chosen contaminant. It also assesses how the ZVI-based technology may be applied in complex, natural systems, the limitations to implementation, and possible avenues for further research which might improve the viability of the process., The book covers the recently discovered oxidative process driven by zero-valent iron (ZVI) in the presence of oxygen and a further developed system which is named ZEA (Zero-valent iron, EDTA, Air). Future potential applications for en- ronmentalremediationusingthisprocessarealsodiscussed. Theoxidativeprocess wasdiscoveredduringthecourseofmolinate(athiocarbamateherbicide)degra- tion experiments.

Both ferrous iron and superoxide (or, at pH < 4. 8, hydroperoxy) radicals appear to be generated on corrosion of the ZVI with resultant production of strongly oxidizing entities capable of degrading the trace contaminant.

Toassessthepotential applicationofnZVIforoxidativetransformationoforganiccontaminants,thec- version of benzoic acid (BA) to p-hydroxybenzoic acid (p-HBA) was used as a probe reaction. When nZVI was added to BA-containing water, an initial pulse of p-HBA was detected during the ?rst 30 minutes, followed by the slow generation of additional p-HBA over periods of at least 24 hours. The ZEA system showed that chlorinated phenols, organophosphorus and EDTA have been degraded. The mechanism by which the ZEA reaction proceeds is hypothesized to be through reactive oxygen intermediates. The ZVI-mediated oxidation and ZEA system may be useful for in situ applications of nZVI particles and may also provide a means of oxidizing organic contaminants in granular ZVI-containing permeable reactive barriers. The purpose of this book is to provide information on the recently discovered chemical process, which could revolutionize the treatment of pesticides and c- taminated water. It also aims to offer signi'cant insights to the knowledge for potential applications of ZVI-based technology. Oxidative degradation of herbicides (e. g.
