Detection of plastics in water based on their fluorescence behavior
AI summary Read the abstract
Researchers investigated whether plastics could be detected and identified in tap water under laboratory conditions using fluorescence spectroscopy based on their characteristic emission properties. The study found that fluorescence behavior offers a potential new tool for detecting plastic contamination in water.
Abstract. Plastic waste is one of the biggest growing factors contributing to environmental pollution. So far there has been no established method to detect and identify plastics in environmental matrices. Thus, a method based on their characteristic fluorescence behavior is used to investigate whether plastics can be detected and identified in tap water under laboratory conditions. The experiments show that the identification of plastics as a function of water depth is possible. As the identification becomes more difficult with higher water depths, investigations with a highly sensitive imaging method were carried out to obtain an areal integration of the fluorescent light and thus better results.
