Investigating the Potential of UV-excited Photoluminescence Spectroscopy for the Identification of Plastics
Gies S., Schömann E., Radiev Y., Prume J., (Corresponding) Koch M.
Topic:
Microplastics in the marine environment
In this study, we investigate photoluminescence (PL) spectroscopy with UV excitation as an alternative method for the detection and identification of plastic materials. The PL is excited at 266 nm. Spectra of the most widely used plastic materials are analyzed. Based on these results, it should be...Read more
Affordable multi-spectral imaging system for the identification and classification of microplastics from the environment

Topic:
Case studies of macro- and microplastics pollution in coastal waters and rivers
Studies on microplastic pollution commonly use expensive spectroscopic methods such as FTIR spectroscopy or Raman spectroscopy. Alternatively, studies could also employ cheaper methods such as optical microscopes, which are prone to errors. Here, we present an inexpensive and simple multi-spectral...Read more

Photoluminescence spectroscopy on commercially available plastic products
(Corresponding) Konde S., Brackmann S., Hüppe F., Koch M.
Topic:
Case studies of macro- and microplastics pollution in coastal waters and rivers
Commercially available plastic products are produced for specific applications. They represent polymeric compounds, i.e. base materials mixed with various types of additives such as pigments. The identification of the plastic type is the key goal in microplastics analysis but also the key process...Read more
