Detection and Classification of Microplastics Using LIBS
AI summary Read the abstract
Researchers explored using laser-induced breakdown spectroscopy (LIBS) to rapidly detect and classify microplastics in the environment, a step toward more efficient plastic waste recovery and recycling. Improved detection tools are essential for tracking where microplastics accumulate and assessing cleanup strategies.
The recovery, classification, and proper recycling of microplastics in the environment are considered one of the most pressing, and difficult, tasks towards a better environmental sustainability of our modern society. In this chapter, we will discuss how...
