Pyridinium-Functionalized Ionic Porous Organic Polymer for Rapid Scavenging of Oxoanions from Water.

Metal oxoanions adversely affect the food chain through bioaccumulation and biomagnification. Therefore, they are among the major freshwater contaminants that require immediate remediation. Although several adsorbents are developed over the years for sequestering these micropollutants, the selective removal of oxoanions remains still a formidable challenge.
