Results of XRD Analysis Summary Nanotechnology not only represents the cutting edge of research in chemistry, but also has been of considerable interest in other multidisciplinary research areas such as biochemistry, medicine [for cancer detection and treatment], and materials science. Iron, which is widely available, has been used in a variety of areas, and recently nanoscale iron research has received significant interest. The newly discovered advanced oxidation technology using nanoscale zero-valent iron, which is reported in this book, could be widely used to treat pesticides, herbicides, and industrial chemicals as well as to purify contaminated water for domestic use. In addition, it can contribute to advancing science and technology and providing valuable information to all readers - researchers, scientists, engineers, and students - in this field for their further research and studies Analysis chemie chemistry milieu environment afvalwaterbehandeling waste water treatment waterbeheer water management analytische scheikunde analytical chemistry anorganische scheikunde inorganic chemistry nanotechnologie nanotechnology Chemistry (General) Chemie (algemeen) Bibliography Includes bibliographical references (pages 129-146) and index Notes Print version record In Springer e-books Subject In situ remediation.
