Modified biomaterials were prepared by various facile synthetic strategies such as cross-linking and composite formation. This has led to the development of adsorbent materials with unique physicochemical properties for the controlled removal of waterborne contaminants. This presentation will focus on several case studies of modified biomaterials developed by Wilson’s research group that demonstrate the unique adsorption properties at equilibrium and at dynamic conditions. Our results reveal that modified biomaterials possess high uptake and improvement in adsorption properties with responsiveness toward external conditions (temperature, pH, magnetic fields, etc.). Our studies illustrate the unique properties of modified biomaterials for advanced water treatment applications at variable scale to address chemical aspects of global water security. Several examples will show how an understanding of the functional properties of biomaterials relate to the “catch and release” of organic and inorganic waterborne contaminants for applications ranging from chemical fractionation of species with variable hydrophile-lipohile character to environmental remediation of targeted species (petrochemicals, fertilizers, detergents, etc.) in aquatic environments. 

Dr. Lee D. Wilson (PhD) is an Associate professor in the department of chemistry at the University of Saskatchewan with research interests in physical chemistry and macromolecular systems. Wilson’s research is in the area of Physical Chemistry, Materials & Environmental Science where current efforts are being directed at the development of new types of materials such as molecular sponges and their structure-function relationships. Molecular sponge materials will have a tremendous impact on areas such as the environment, biotechnology, medicine, chemical delivery/separation systems, and membrane materials for water purification where the fate and transport can be altered through adsorption-based processes. This research will contribute to global water security where improved adsorbent materials will lead to the controlled removal of chemical contaminants using point-of-use treatment strategies and sustainable green science and technology.
