Size Characterization and Detection of Aerosolized Nanoplastics Originating from Evaporated...

Description:

Mass production of plastic products has led to an environmental problem on global scale. However, knowledge about pathways into the environment and the generation mechanisms of plastic-derived nanoparticles is scarce. Controlled generation methods of aerosolized nanoplastics are needed to enable further research. In this talk, a method for the controlled generation of aerosolized nanoplastics using a tube furnace will be presented. The experimental approach will be outlined and particle number size distributions originating from a selection of higher-purity and commodity plastics will be discussed. Additionally, the influence of experimental parameters (flow rate, amount of material, and the setpoint temperature of the tube furnace) on the particle number size distributions of polyethylene terephthalate (PET)-derived nanoparticles will be addressed in more detail.
