ABSTRACT

Recent years have seen a vast interest in developing simple, cost-effective and greener methods for the preparation of efficient water treatment solutions utilizing naturally abundant and renewable resources. Sustainable and greener technologies have enabled the utilization of several natural and synthetic stocks of materials as efficient water treatment media. Functional nanomaterials have gained increased attention in recent times due to their selective separation of emerging pollutants (EPs) from various contaminated sources. Functional materials in nano-, micro- and bulk levels have been tuned to capture series of EPs from different sources. Polymer, carbaneous precursors, nanomaterials, 2D nanomaterials and high surfaces are layered structures, such as MOFs, ZIFs and LDHs, and blends and composites of these materials in various combinations and compositions have been prepared and successfully used for EP removal from various water and wastewater sources. Some of these material stocks have also been used in gel, aerogel and ion-exchange membrane forms. This chapter gives an overview of the wide range of material stock used for water treatment application following the appropriate functionalization process.
