Resumo: | Waste electrical and electronic equipment (WEEE) is among the fastest growing types of solid waste in the world. In addition, this is a complex waste stream when it comes to recycling, due to the large variety of valuable materials and toxic elements present in plastics, metals, glass, ceramics, etc. In this context, the chemical analysis of electronic waste and issues involving the management of this matrix were discussed in this thesis: (1) initially, bibliometric resources were used to evaluate the different topics involving the handling of electronic waste and the evolution of world research; (2) as well, given the lack and difficulty of producing materials to ensure the traceability of measurements and validation of analytical methods, an electronic waste reference material was produced and evaluated following all standards established by ISO guides 30 - 35; (3) finally, different techniques of direct analysis such as laser-induced breakdown spectroscopy (LIBS), laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) and X-ray spectrometry (XRF) were used to develop analytical methods for elementary determination in printed circuit board (PCB) and liquid crystal display (LCD) samples. Bibliometrics proved to be an efficient resource for analyzing past research topics, emerging research hotspots and assess the current status of electronic waste research. Studies involving the analysis of critical elements (e.g. In, Pd, rare earths) and the development of reference materials for e-waste have been identified as gaps in the current literature, which are addressed and discussed in this thesis. New univariate (multi-energy calibration, MEC) and multivariate (data fusion using partial least squares regression, PLS) calibration strategies have been proposed for direct analysis of e-waste samples (i.e. PCB and LCD), through elemental analysis and chemical mapping within the sample surfaces. Considering the applicability, advantages and limitations of each analytical technique used, combined with appropriate chemometric tools, it was possible to propose new methods for analyzing complex matrices such as e-waste, which make it possible to minimize or even eliminate possible interferences, with analytical performance similar or superior to those existing traditional alternatives. |

Além disso, este é um fluxo de resíduo complexo quando se trata de reciclagem, devido à grande variedade de materiais valiosos e elementos tóxicos presentes em plásticos, metais, vidro, cerâmicas, etc. Nesse contexto, a análise química do resíduo eletrônico e assuntos que envolvem o manejo dessa matriz foram discutidos nessa tese: (1) inicialmente foi empregado recursos bibliométricos para avaliar os diferentes temas que envolvem o manejo do lixo eletrônico e a evolução da pesquisa mundial; (2) assim como, dado a falta e dificuldade de produção de materiais para assegurar a rastreabilidade de medições e validação de métodos analíticos, um candidato a material de referência de resíduo eletrônico foi produzido e avaliado seguindo as normas definidas pelas guias ISO 30-35; (3) por fim, diferentes técnicas de análise direta, tais como laser-induced breakdown spectroscopy (LIBS), laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) e X-ray spectrometry (XRF) foram empregadas para desenvolvimento de procedimentos analíticos visando a determinação elementar em amostras de placas de circuito impresso (PCB) e telas de cristal líquido (LCD). A bibliometria mostrou-se como um recurso eficiente para analisar tópicos antigos, temas emergentes e avaliar o status atual da pesquisa sobre resíduos eletrônicos. Estudos envolvendo a análise de elementos críticos (e.g. In, Pd, terras raras) e desenvolvimento de materiais de referência para resíduo eletrônico foram identificados como lacunas da literatura atual, os quais foram abordados e discutidos nessa tese. Novas estratégias de calibração univariada (multi-energy calibration, MEC) e multivariada (fusão de dados usando regressão por mínimos quadrados parciais, PLS) foram propostas para análise direta dessas amostras (i.e. PCB e LCD), através da análise elementar e mapeamento químico da superfície das amostras. Considerando a aplicabilidade, vantagens e limitações de cada técnica analítica empregada, combinado a ferramentas quimiométricas adequadas, foi possível propor novos métodos de análise de matrizes complexas como o resíduo eletrônico, que possibilitam minimizar ou mesmo eliminar possíveis interferências, com desempenho analítico semelhante ou superior às alternativas tradicionais existentes.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)2016/17304-0engUniversidade Federal de São CarlosCâmpus São CarlosPrograma de Pós-Graduação em Química - PPGQUFSCarAttribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/info:eu-repo/semantics/openAccessLixo eletrônicoAnálise bibliométricaMaterial de referência certificadoLIBSLA-ICP-MSXRFE-wasteBibliometric analysisCertified reference materialCIENCIAS EXATAS E DA TERRA::QUIMICAPrecious, strategic and toxic elements in electronic waste: bibliometric evaluation, proposition of reference material and direct analysis by laser-based techniques and fluorescence spectrometryElementos preciosos, estratégicos e tóxicos em resíduos eletrônicos: avaliação bibliométrica, proposição de material de referência e análise direta por técnicas baseadas em laser e espectrometria de fluorescênciainfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisreponame:Repositório Institucional da UFSCARinstname:Universidade Federal de São Carlos (UFSCAR)instacron:UFSCARORIGINALTese_DFA_vf_210401.pdfTese_DFA_vf_210401.pdfapplication/pdf9310632https://repositorio.ufscar.br/bitstream/ufscar/17116/1/Tese_DFA_vf_210401.pdf2bf3b8c7e7bc50b0e36b440eae354e6bMD51carta_comprovante_DFA_tese_assinado.pdfcarta_comprovante_DFA_tese_assinado.pdfCarta comprovante teseapplication/pdf168903https://repositorio.ufscar.br/bitstream/ufscar/17116/3/carta_comprovante_DFA_tese_assinado.pdfce1bd9c37bfe97a807a27224038b4cd8MD53CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml; charset=utf-8811https://repositorio.ufscar.br/bitstream/ufscar/17116/4/license_rdfe39d27027a6cc9cb039ad269a5db8e34MD54TEXTTese_DFA_vf_210401.pdf.txtTese_DFA_vf_210401.pdf.txtExtracted texttext/plain335651https://repositorio.ufscar.br/bitstream/ufscar/17116/5/Tese_DFA_vf_210401.pdf.txt705d0ca4f3cffdf392575d22e7b3e5b1MD55carta_comprovante_DFA_tese_assinado.pdf.txtcarta_comprovante_DFA_tese_assinado.pdf.txtExtracted texttext/plain1505https://repositorio.ufscar.br/bitstream/ufscar/17116/7/carta_comprovante_DFA_tese_assinado.pdf.txtfae3d6fdf311728164f4d0380118dcdfMD57THUMBNAILTese_DFA_vf_210401.pdf.jpgTese_DFA_vf_210401.pdf.jpgIM Thumbnailimage/jpeg9255https://repositorio.ufscar.br/bitstream/ufscar/17116/6/Tese_DFA_vf_210401.pdf.jpg34a674b3d3e89143fe5bd35cae184f5aMD56carta_comprovante_DFA_tese_assinado.pdf.jpgcarta_comprovante_DFA_tese_assinado.pdf.jpgIM Thumbnailimage/jpeg12308https://repositorio.ufscar.br/bitstream/ufscar/17116/8/carta_comprovante_DFA_tese_assinado.pdf.jpgfaba12363f9ebff4e55573f5cc561544MD58ufscar/171162022-12-06 03:39:38.834oai:repositorio.ufscar.br:ufscar/17116Repositório InstitucionalPUBhttps://repositorio.ufscar.br/oai/requestopendoar:43222023-05-25T13:04:58.952332Repositório Institucional da UFSCAR - Universidade Federal de São Carlos (UFSCAR)false |
