Analysis of the polymeric fractions of scrap from mobile phones using laser-induced breakdown spectroscopy: Chemometric applications for better data interpretation

A critical review of recent progress in analytical laser-induced breakdown spectroscopy

“…overall accuracy, robustness, or number of true and false-positive cases) should be described. Systematic studies comparing the performance of several classification methods on the same LIBS datasets are still rare [110][111][112][113], although these studies would be indispensable in assisting the selection of chemometric methods for wide use in LIBS.…”

Mobile phone waste management and recycling: Views and trends

“…Plastic codes were also considered for initial identification. Aquino and Pereira-filho (2015) analyzed polymers in mobile phones by LIBS technique (Laser Induced Breakdown Spectroscopy) in combination with chemometric tools and the repeatability of the test was found to be good.…”

Identification and thermomechanical characterization of polymers recovered from mobile phone waste

“…As a futuristic work, one can grind the elastomeric components recovered from mobile phones, such as elastomeric keypads, to a fine powder, which can be incorporated as a toughening agent within the recovered plastics to improve their impact strength. Also, nowadays, advanced identification techniques such as laser-induced breakdown spectroscopy (LIBS) and FTIR in combination with chemometric tools are available for identification of WEEE plastics [30][31][32]. Such advanced techniques may be employed in future.…”
