Klappentext This book will give the solution to water demand and also the low cost, low energy, novel bio adsorbents-based techniques for the water treatment. It serves as a comprehensive guide for removing various types of contaminants at any concentration and covers many types of biomasses from which bio-adsorbents can be prepared. Finally, the book provides insights into the pros and cons of each bio-adsorbent, their synthesis method, and their characterization. Additionally, it addresses the life cycle assessment, economics, and environmental impacts of bio-adsorbents, all within one comprehensive resource. Topics covered in the book include the Biomass derived adsorbents, Synthesis techniques of novel Bio-adsorbents, Nanotechnology-Based Nano-Biosorbents, Characterization techniques of Bio-adsorbents, Application of Bio-adsorbents in waste water treatment, Bio-adsorbents in dye removal, heavy metal removal and emerging contaminants, and Economics and environmental aspects of Bio-adsorbents.
