Download or read book Nanoscale Zerovalent Iron Particles for Environmental Restoration written by Tanapon Phenrat and published by Springer. This book was released on 2019-01-31 with total page 611 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first complete edited volume devoted to providing comprehensive and state-of-the art descriptions of science principles and pilot- and field-scaled engineering applications of nanoscale zerovalent iron particles (NZVI) for soil and groundwater remediation. Although several books on environmental nanotechnology contain chapters of NZVI for environmental remediation (Wiesner and Bottero (2007); Geiger and Carvalho-Knighton (2009); Diallo et al. (2009); Ram et al. (2011)), none of them include a comprehensive treatment of the fundamental and applied aspects of NZVI applications. Most devote a chapter or two discussing a contemporary aspect of NZVI. In addition, environmental nanotechnology has a broad audience including environmental engineers and scientists, geochemists, material scientists, physicists, chemists, biologists, ecologists and toxicologists. None of the current books contain enough background material for such multidisciplinary readers, making it difficult for a graduate student or even an experienced researcher or environmental remediation practitioner new to nanotechnology to catch up with the massive, undigested literature. This prohibits the reader from gaining a complete understanding of NZVI science and technology. In this volume, the sixteen chapters are based on more than two decades of laboratory research and development and field-scaled demonstrations of NZVI implementation. The authors of each chapter are leading researchers and/or practitioners in NZVI technology. This book aims to be an important resource for all levels of audiences, i.e. graduate students, experienced environmental and nanotechnology researchers, and practitioners evaluating environmental remediation, as it is designed to involve everything from basic to advanced concepts.

Download or read book Iron Nanomaterials for Water and Soil Treatment written by Marta I. Litter and published by CRC Press. This book was released on 2018-09-03 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanotechnology has a great potential for providing efficient, cost-effective, and environmentally acceptable solutions to face the increasing requirements on quality and quantity of fresh water for industrial, agricultural, or human use. Iron nanomaterials, either zerovalent iron (nZVI) or iron oxides (nFeOx), present key physicochemical properties that make them particularly attractive as contaminant removal agents for water and soil cleaning. The large surface area of these nanoparticles imparts high sorption capacity to them, along with the ability to be functionalized for the enhancement of their affinity and selectivity. However, one of the most important properties is the outstanding capacity to act as redox-active materials, transforming the pollutants to less noxious chemical species by either oxidation or reduction, such as reduction of Cr(VI) to Cr(III) and dehalogenation of hydrocarbons. This book focuses on the methods of preparation of iron nanomaterials that can carry out contaminant removal processes and the use of these nanoparticles for cleaning waters and soils. It carefully explains the different aspects of the synthesis and characterization of iron nanoparticles and methods to evaluate their ability to remove contaminants, along with practical deployment. It overviews the advantages and disadvantages of using iron-based nanomaterials and presents a vision for the future of this nanotechnology. While this is an easy-to-understand book for beginners, it provides the latest updates to experts of this field. It also opens a multidisciplinary scope for engineers, scientists, and undergraduate and postgraduate students. Although there are a number of books published on the subject of nanomaterials, not too many of them are especially devoted to iron materials, which are rather of low cost, are nontoxic, and can be prepared easily and envisaged to be used in a large variety of applications. The literature has scarce reviews on preparation of iron nanoparticles from natural sources and lacks emphasis on the different processes, such as adsorption, redox pathways, and ionic exchange, taking place in the removal of different pollutants. Reports and mechanisms on soil treatment are not commonly found in the literature. This book opens a multidisciplinary scope for engineers and scientists and also for undergraduate or postgraduate students.

Download or read book Iron-based Nanoparticles: Investigating the Nanostructure, Surface Chemistry, and Reactions with Environmental Contaminants written by Weile Yan and published by . This book was released on 2011 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanoscale zero-valent iron (nZVI) is one of the most extensively applied nanomaterials for groundwater and hazardous waste treatment. Despite its high potential for environmental applications, there is limited knowledge about the fundamental properties of nZVI, particularly, its structure, surface composition, and changes in these characteristics in the aqueous media as the nanoparticles interact with aqueous contaminants. This research aims to investigate the structure and surface chemistry of nZVI and to understand how these attributes influence the material's reactivity towards various water contaminants. This work first involved a detailed examination of the metallic-core-oxide-shell structure using a variety of microscopic and spectroscopic tools. It was found that the polycrystalline metallic iron nuclei are spontaneously enclosed by a disordered layer of iron oxide that is 2--3 nm thick. Using a group of water contaminants (Hg(II), Zn(II) and hydrogen sulfide) as molecular probes, it was shown that the nanoparticles were able to utilize multiple pathways including adsorption, precipitation, reduction and surface mineralization to effectively immobilize these contaminants. The observed multiplexed reactivity is imparted by the particular core-shell configuration allowing both the oxide and metal components to exert their reactive tendency without undue kinetic hindrance. The second theme of this research was to examine the structural changes experienced by Pd-doped nZVI during exposure to aqueous media. With scanning-TEM X-ray energy-dispersive spectroscopy (STEM-XEDS), the translocation of Pd from the surface to regions underneath the oxide layer and the rapid loss of the Fe(0) core due to accelerated aqueous corrosion were observed. The morphological changes resulted in a severe reduction in the reductive dechlorination rate of trichloroethylene (TCE), suggesting that the activity of Pd-doped nZVI is a dynamic function of time and particle structure. The close relationship between the structure and reactivity of nZVI is further illustrated by reactions with aqueous arsenite (As(III)). Notably, nZVI caused simultaneous oxidation and reduction of arsenite in the solid phase. Using depth-resolved high-resolution X-ray photoelectron spectroscopy (HR-XPS), multi-layered distributions of different arsenic valence states in the nanoparticles were observed, where the oxidized arsenic (As(V)) was predominantly present at the surface and the reduced form (As(0)) was located at the oxide/metal interface. The observed dual redox capability is therefore enabled by the metal core and oxide layer independently. The findings presented in this work establish that nZVI possesses more complex functionality than bulk-scale ZVI or iron oxides. The improved understanding of sequestration mechanisms studied here may inform optimal design of nZVI treatment systems and aid development of materials and new applications.

Book excerpt: The thesis is comprised of three distinct phases. In the first phase of the research, synthesis of nZVI using fruit waste, namely the mango peel extract was carried out. Then, the role in contaminant remediation of the synthesized nZVI particle was evaluated using environmentally relevant contaminants; i.e. examining the role of the newly synthesized nZVI for catalytic oxidation of total petroleum hydrocarbons in oily sludge contaminated soil and for the reductive removal of aqueous solutions of chromium VI. Due to the dramatic increase in the production and use for environmental remediation, studies lacking the toxicological information of the commercial forms of iron containing nanoparticles to terrestrial organisms had also been carried out. Therefore, phase three is focused on evaluation of the risks of using nZVI for environmental remediation.
