Preface

Environmental analysis has become a topic of considerable importance these days. It is not only significant to environmentalists but also to regulators, decision makers, surveillance agencies and the organizations assessing the impact of pollutants on the environment, and it has evolved as a true discipline throughout the world. In recent years, there has been a rapid union of nanotechnology and analytical sciences. This convergence, although highly interdisciplinary in nature, has been brought about by new technologies that have led to application-specific devices, for example lab-on-a chip. The high demand for advanced comprehensive understanding and awareness of more accurate and precise measurement tools for pollutants and their characterization dictate the terms and conditions for this convergence. The reduction in size from bulk to micro- and nano-scale promises high sensitivity, high speed, increased selectivity and increased device lifetime for new devices. Instruments with more sensitivity are required today to analyze ultra-trace levels of environmental pollutants, pathogens in water, and low vapor pressure energetic materials in air.

The objective of this book is to provide an overview of new developments for a variety of environmental analytical techniques. Every effort has been made to include the state-of-the-art to show improvements in environmental analytical techniques and processes due to nanomaterials in the book. Additionally, special attention is paid to those approaches that are green and reduce the cost of the analysis, process both in terms of chemicals and time consumption. In the end the legal, economical and toxicity aspects of nanomaterials are also presented in detail.

To put all of the shared knowledge into perspective, add a touch of reality to the concepts, and to cover extensive expansion of the applications of nanomaterials in the environmental analysis field, the book is divided into two volumes and each volume has subdivisions of several sections. Moreover, to

maintain coherence in the flow of knowledge, these sections are patterned in a continuous manner in both volumes. As a result, sections one to four are contained in the first volume, whereas sections five to ten are provided in the second volume.

In Volume One, the first section talks about the perspective of analytical sciences in relation to nanotechnology, synthetic techniques for nanomaterials, different unique properties of nanomaterials and a detailed description of the mechanisms of adsorption on nanomaterials. The second section encompasses the recent advances in sample preparation and extraction techniques for organic and inorganic pollutants with nanomaterials. The third section is all about new developments in separation techniques with a focus on applications of nanomaterials for chromatography and membrane technology. The fourth section incorporates spectroscopic techniques using nanomaterials, especially surface-enhanced Raman scattering (SERS), for detection of environmental pollutants.

In Volume Two, the fifth section describes new trends in environmental analysis, i.e., applications of magnetic nanomaterials, nano-sensors, composite materials and nano-bio sensors, like nanozymes. The sixth section talks about the applications of nanomaterials for water treatment and purification techniques. The effects of nanomaterials on the environment and the ecosystem in terms of their toxicity, safety regulations and economic issues are depicted in the seventh section. Section eight discusses the monitoring and analysis of nanomaterials, whereas section nine is about the future of environmental analysis in light of new developments in science and technology. In the last section, the editors provide concluding remarks about the application of nanomaterials for environmental analysis.

The selection of these sections in both volumes is based on the most recent research, teaching, the practical experience of editors and the philosophy that environmental analysis is moving towards its next generation. The contributing authors are selected from a wide cross-section around the world. The diversity of authors for each chapter and their disciplinary backgrounds reveal the interdisciplinary emphasis of this book. Thanks to the multidisciplinary nature of this book, the reader can enjoy a lot of knowledge in one place.

The anticipated audience is scientists, researchers, consultants, regulators and engineers. Moreover, graduate students will find this book to be very useful in their research and understanding of advances in environmental analysis techniques and beyond. The book is also intended to provide more experienced researchers with a condensed summary of the influence of nanotechnology on analytical techniques and excellent up-to-date references that will prove useful in their future endeavors. The editors and contributors are lead scientists and researchers in academia and industry in their subject areas. On behalf of the Royal Society of Chemistry, we are very thankful to all contributors for their special and hard work in the making of this book.

19.1 Introduction

Magnetic nanomaterials (MnMs) have widespread applications in biotechnology, biomedical, material science, engineering, and environmental areas. therefore, considerable attention has been given to their synthesis methods. MnMs as sorbents have been extensively exploited as materials of choice to separate biological cells and isolate proteins, enzymes or peptides. separation techniques with magnetic nanomaterials are usually gentle and nondestructive to analytes, and even large complexes that tend to be broken up in the process of traditional column chromatography may remain active. Furthermore, magnetic separation can be easily and directly used for raw samples with several simple steps. recently, different kinds of magnetic nanomaterials have been rapidly and extensively developed, and widely used in analytical techniques. MnMs are superparamagnetic so can attract a magnetic field, but retain no residual magnetism after the field is removed. therefore, it is easy to isolate MnMs stuck to analytes from a sample solution or complicated matrices by simply applying an external magnetic field and this requires no filtration or centrifugation. in this chapter, factors

influencing contaminant removal by magnetic nanoparticles are reviewed and to reduce the treatment cost, the feasibility of the reuse and recovery of magnetic nanoparticles is also discussed.1,2

Compared with conventional separation techniques, there is no need for packing of the column with the sorbent, since the phase separation can be quickly and easily accomplished by applying an external magnetic field. there are a few problems associated with particles at the nano range, i.e., their intrinsic instability, which tends to lead to formation of agglomerates. Moreover, uncovered metallic nanomaterials are chemically highly active and are easily oxidized in air, which results in loss of magnetism and dispersibility. the critical part is to develop shield approaches to chemically stabilize the isolated magnetic nanomaterials. Grafting or coating with an inorganic layer, like silica or carbon, or coating with organics, like surfactants and polymers, are a few shield approaches that have been utilized. in most of these approaches, the shielding shells not only stabilize the nMs but can also offer opportunity for additional functionalization. in summary, magnetic nanomaterials in environmental analysis are able to facilitate or accelerate many extraction and purification procedures and efficiently combine with the majority of other procedures used in environmental analysis.3,4

19.2 Properties and Format of Magnetic Nanomaterials

the properties of magnetic materials were identified early in the sixth century BC, but the first patent was filed by William Fullarton relating to the separation of iron minerals with a magnet in 1792. application for the separation and analysis of various biologically active compounds and cells using magnetic materials was started in the 1970s. since then, an increasing number of studies have focused on magnetic separation and analysis of biological samples using magnetic materials. Figure 19.1 shows the data of published articles on magnetic separation of proteins/peptides, nucleic acids, cells, and bioactive compounds and immobilization of enzymes from 2003 to 2013.5 there are two main ways of performing magnetic separation of analytes. in the first circumstance, no special modification of the target is needed when dealing with those exhibiting sufficient intrinsic magnetic moments involving some paramagnetic or ferromagnetic biomolecules or cells, such as ferritin, hemoglobin and deoxygenated erythrocytes (in plasma). in the second case, when coping with diamagnetic molecules and supramolecular structures, suitable magnetic modifications should be performed in order to attach magnetic labels to targets or immobilize targets to magnetic carriers or adsorbents. the linkage of magnetic labels to the targets is often mediated by affinity ligands or other types of interactions.5,6 in general, there are two modes for magnetic separation, i.e., direct or indirect (Figure 19.2).5 in the direct mode, magnetic affinity particles that possess appropriate affinity ligands and exhibit affinity toward the target
