The fate and transport of oxyanion species such as orthophosphate (Pi) in aquatic environments is gaining greater concern for agriculture, industry, and aquatic environments. The uncontrolled release and buildup of nutrients such as Pi and other oxyanions in aquatic environments have unintended effects such as eutrophication that pose a concern for global water security. Synthetic modification of biopolymers provide an opportunity to design improved polymer materials for the controlled removal of oxyanion species in aqueous media. This presentation will provide an outline of recent developments at the University of Saskatchewan (U of S) related to studies focused on the synthesis and characterization of modified biopolymer materials and their application as adsorbents. Synthetic modification via surface functionalization, cross-linking, and composite formation of various biopolymers have led to materials with enhanced physicochemical properties related to adsorption. Case studies of biopolymer materials will highlight their responsive behaviour to external stimuli (pH, ionic strength, temperature, etc.) and evidence of the unique adsorption properties of such materials toward oxyanions in aqueous media. The examples described herein reveal that such studies contribute to the field of advanced polymer materials.
