Description

Green Technologies for the Defluoridation of Water focusses on the application of green technologies for de-fluoridation of water using adsorption processes and nanoadsorbents. To achieve this objective the content is structures into five parts. Chap 1 covers the Environmental and health effects of fluoride presence in ambient air, food, water, soil and vegetation. Chap II focuses on the approaches for analytical methods to determine the presence of flouride in water. Chap III reviews various types of conventional and advanced techniques that were used for removal of fluoride from water. Chap IV focusses on Adsorption as a green technology for removal of fluoride from water. Chap V reviews various types of adsorbents that can be used for removal of fluoride. Chap VI emphasizes on the techno-economic assessment of removal of fluoride from water with respect to conventional and non-conventional technologies. Finally, Chap VII emphasizes a detailed assessment of global water challenges and opportunities that may arise.

Green Technologies for the Defluoridation of Water provides methods and applications and presents global impacts of fluoride ion in environment including drinking water, food, air, soil and vegetables. The authors compare different de-fluoridation technologies in detail, providing researchers in environmental science and nanotechnology field the information they need to provide solutions to the issue of removing fluoride from water safely, sustainably and cost effectively.
