|Title: Design of Modified Biosorbent Materials with Tunable Properties|
Modified biomaterials were prepared by cross-linking and formation of composites with
unique physicochemical properties suitable as sorbents for a wide range of waterborne contaminants.
Materials with diverse structure and textural properties were obtained by varying the type of
cross-linker and second component in the case of composite materials. Structural characterization
and adsorption properties were investigated by various molecular level methods. This presentation
will cover recent studies that illustrate the unique and tunable adsorption properties of such
biosorbent materials. These studies illustrate the responsive properties of advanced biomaterials and
insight concerning their structure-activity relationship related to adsorption properties toward
organic and inorganic waterborne contaminants in aqueous media.

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 sponge materials and their structure-function relationships. Molecular sponge materials derived from biopolymers and their modified forms will have a tremendous impact on areas such as the environment, biotechnology, medicine, chemical delivery/separation systems, and membrane materials for water purification.
