The detection of trace concentrations of emerging contaminants in the environment has been a serious concern in the past decades. Emerging contaminants (ECs) are a group of pollutants that can have lethal impact on human and wildlife endocrine systems, even if available at trace quantities. Conventional treatments and natural attenuation are not able to remove these pollutants from the environment and therefore, they eventually end up in human food chain. An in-depth review has been done on the engineering perspective of adsorption process for the removal of ECs from aqueous solutions. The results of the review indicate that adsorption is a potential technology for the removal of a wide range of contaminants of emerging concern. This book chapter provides a holistic assessment on the sources and categories of ECs, adsorption as a potential technology for their removal, along with the mechanisms of adsorption. Furthermore, we made an attempt to critically discuss various adsorption mechanisms involved during the removal of the contaminants from water streams as well as provided a perspective of the use and importance of artificial neural networks in adsorption technology. Finally, an attempt has been made to critically discuss the potential of widely acknowledged adsorbents in removing ECs and to perform an assessment of the techno-economic feasibility of using biochar as an effective sorbent.
