Development of a Cost-Effective and Eco-Friendly Method for Removal of 6DDP-quinone, a Tire Rubber-Derived Emerging Pollutant from Saskatoon Stormwater

Stormwater outfalls are point sources containing various pollutants from urban environments that are often discharged directly into rivers. Previous research at University of Saskatchewan showed considerable concentrations of 2-anilo-5-[(4-methylpentan-2- yl)amino]cyclohexa-2,5-diene-1,4-dione (6PPD-quinone), a tire rubber-derived compound, in Saskatoon’s stormwater. 6PPD-quinone is an emerging pollutant of concern that is highly toxic to fish. Adsorption is a promising approach to remove emerging pollutants from water. This research aims to develop a cost-effective and eco-friendly adsorbent using agricultural residues. This adsorbent will be assessed for its ability to remove 6PPD-quinone from urban runoff in Saskatoon, thus, it can then be employed to minimize its release into the South Saskatchewan River.
