Given the rising crisis ensuing from environmental contaminations mostly as a result of industrial and domestic activities as well as the significant amount of these contaminants released from both natural and anthropogenic activities into the environment, in particular water bodies, without appropriate treatment, which subsequently find their way into the soil and disrupt both atmospheric, aquatic, and terrestrial systems, there is an optimum necessity for innovative approaches using biosorbents such as bio-nanocomposite for the confiscation of these contaminants owing to their exclusive features such as biocompatibility, biodegradability, and renewability. Hence, this anticipates presenting a basis on the developments, utilization, and applications of adsorption of contaminants (such as heavy metals and dyes) using biosorbents for environmental sustainability and safety.

The book is made up of fifteen (15) chapters that particularly focus on advanced research in the use of nanotechnology in the synthesis of novel biosorbents using facile synthesis methods, the use of analytical spectroscopic techniques for their characterization, and the extensive applications of the synthesized biosorbents in the remediation and photocatalytic degradation of contaminants (such as noxious metal ions and dye molecules).

Highlights on the types, characteristics, and management options (reusability, recyclability, and final disposal) of commonly used adsorbents in environmental sustainability are also discussed. Also covered are the cost and environmental evaluations and comparisons of commonly used sorbents, as well as the future scopes of adsorption applications for environmental sustainability.
