In-line characterization of microplastics via autofluorescent spectroscopy

Microplastics are emerging anthropogenic particulate pollutants that pose risks to both societal and environmental health. As such, there is a need to characterize the distribution of microplastics both within the environment and at potential points of release. Current analytical techniques – primarily thermogravimetric analysis, Raman spectroscopy, and infrared spectroscopy – used to characterize microplastics offer precision but are time consuming processes, both in sample preparation and analysis. This project will develop a novel spectroscopic analytical technique that utilizes the cluster-triggered fluorescent emission of the target particles. It will assess whether synthetic polymers can be distinguished from one another, as well as from natural polymers and additives, via the technique and determine the effect of oxidation. Initial success will enable feasibility studies as to whether the fluorescent spectroscopy technique can be applied under flow conditions. This project will bring together the analytical expertise of researchers within the Cranston Sustainable Nano-Biocomposites research group with the industrial capability and knowhow of B.C. Research. A successful project outcome will enable the rapid, in-line analysis of microplastics via autofluorescent spectroscopy.
