“…O objetivo do mapeamento químico geralmente é identificar a posição original dos elementos estudados ao longo de uma amostra, sem nenhum preparo; dessa forma, qualquer preparo, como a moagem e posterior adição de aglutinante para formação de pastilhas, não preservará as informações originais da composição e localização dos elementos na amostra. 45,53 Outra estratégia de preparo de amostras sólidas é a transferência de uma pequena quantidade da amostra em pó para uma fita adesiva. Essa estratégia é recomendada quando a quantidade de amostra não é suficiente para a confecção da pastilha.…”

This review attempts to present a broad view of the technique laser-induced breakdown spectroscopy (LIBS), since its origin, fundamentals, sample preparation strategies, use of chemometric tools for data processing, the advantages and limitations with regard to qualitative and quantitative analysis, aplications and future trends as an analytical technique that is in consolidation in analytical chemistry. LIBS is a rapid and versatile, which is able of providing qualitative and quantitative analytical information for practically any sample, in a virtually non-destructive way, without any substantial sample preparation. The instrumentation is simple, robust, compact, and enables remote analysis. The advancement of the LIBS applications in the areas of agriculture, environmental, food, biological/pharmaceutical, forensic, metallurgy and electronic waste were discussed in detail in this review. We consider that this review will be an important tool concerning dissemination of the LIBS, mainly for audience of undergraduate courses, and disciplines related to instrumental analysis.

“…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.…”

The plastic components from waste mobile phones were sorted and characterized using visual, spectroscopic and thermal methods. The sustainable strength of the recovered plastics was investigated by comparing their mechanical and thermal properties with commercially used reference materials. The results revealed that the recovered polymers have significant potential to be reused. However, some properties, such as impact strength and tensile modulus, are significantly low compared to virgin materials and need further improvement. The samples were also tested for brominated flame retardants (BFRs) using gas chromatography-mass spectrometry technique, and the results indicated the absence of BFR in recovered plastics; hence, these can be processed without any risk of BFR toxicity.
