Dataset for Raman spectra of Microplastics and different aging States
AI summary Read the abstract
Researchers compiled Raman spectra for seven microplastic polymer types across multiple aging states induced by three different weathering treatments, releasing the dataset as a reference library for rapid environmental identification and aging-state characterization of microplastics.
The data set contains 7 kinds of microplastics and microplastics in different aging states under three aging treatments.It can be used as a database for rapid identification and aging research of micro plastics in the environment
