ABSTRACT
The ion-exchange polymers or resins are a versatile class of ion-exchangeable smart materials recently finding importance in water treatment. The polymer-based ion-exchange resins are extensively used in different separation, purification and decontamination processes for water and wastewater sources. Today commercially successful ion-exchange resins found commercially are made of polystyrene-based macromolecular complexes. Conventionally, resins have been widely used for water softening and water purification applications. However, recent advancements and innovations show that ion-exchange resins or polymers in various forms and formats are gaining increased attention due to their potential in treating emerging pollutants. This chapter gives a broader overview of the recent advances on emerging pollutant treatment using ion-exchange materials.
