Primi test per la rivelazione di plastiche in acqua mediante fluorescenza indotta da Laser (LIF)
Summary
Italian researchers conducted feasibility tests for using laser-induced fluorescence (LIF) to rapidly detect and identify microplastics in water, exploring its potential as a lidar-based environmental monitoring tool. The results showed that LIF can distinguish between common plastic types found in the marine environment.
From the environmental point of view the rapid detection of microplastics in water is of primary importance. Here the first feasibility tests carried out for the implementation of a lidar fluorosensor to detect and recognition of plastics in the marine environment are presented. In particular, the ability of the linear scan system LIF (laser induced fluorescence) developed at the FSN-TECFIS-DIM Laboratory of Frascati to detect different plastics samples, among those that are most commonly found in water analysis, through different thicknesses of water have been carried out. The results have provided interesting results, opening the way to more in-depth studies for the development of specific spectroscopic systems for the detection of microplastics in the marine environment without sampling.
