Resumo: The extraction and the gas-solid adsorption behavior of different polycyclic aromatic hydrocarbons (PAHs) were studied in aqueous solution and in four different asphalt petroleum cement (APC) samples, using high-performance liquid chromatography as methodology analysis. Through extraction tests in aqueous solution at 50 ºC, 100% acenaphthene, 87,30% anthracene and 86,23% fluoranthene were emitted. Regarding the emissions of APC samples at 130 ºC, a total of 32,94 mg Kg-1 of total PAHs from the REGAP sample was obtained, which was selected as a representative sample for adsorption studies; 3,37, 3,64 and 1,46 mg Kg-1 of total PAHs of the AMP, REFAP and LUBNOR samples, respectively. Through tests of the evaluation of the retention capacity using three different masses, it was observed in aqueous solution that the, PUF (adsorption yields of 100%) and XAD-2 (adsorption yields>90%) showed the greater retention capacity for PAHs, followed by HDPE (adsorption yields 75-90%). For Si, EVA and GAC, the adsorption yields depended strongly on the PAHs. Alternatively, for the asphalts samples, the adsorption yields decreased for all the evaluated PAHs, showing that the asphalt matrix had the strong influence on the adsorption process, with the total PAHs being 47,20% for PUF, 46,80% for XAD-2, 29,90% for GAC, 27,30% for Si and 19,80% for HDPE. The retention and elution processes on the adsorbent surfaces were also evaluated by atomic force microscopy (AFM).

Por meio dos ensaios de extração em meio aquoso a 50 ºC, obteve-se a emissão de 100% de acenafteno, 87,30% de antraceno e 86,23% de fluoranteno. Em relação as emissões das amostras de CAP a 130 ºC, obteve-se um total de 32,94 mg Kg -1 de HPAs totais da amostra REGAP, sendo essa, selecionada como amostra representativa para estudos de adsorção; 3,37, 2,64 e 1,46 mg Kg-1 de HPAs totais das amostras AMP, REFAP e LUBNOR respectivamente. Através de ensaios da avaliação da capacidade de retenção usando três massas diferentes observou-se em solução aquosa que a EPU (rendimentos de adsorção de 100%) e XAD-2 (rendimentos de adsorção>90%) apresentaram maior capacidade de retenção de HPAs, seguidos por PEAD (rendimentos de adsorção de 75-90%). Para Si, EVA e CAG, os rendimentos dependeram fortemente dos HPAs. No entanto, para as amostras de CAP, o rendimento de adsorção diminuiu para todos os HPAs avaliados, mostrando que a composição da matriz asfáltica teve forte influência no processo de adsorção, sendo a retenção total de HPA foi de 47,2% para EPU, 46,8% para XAD-2, 29,9% para CAG, 27,3% para Si e 19,8% para PEAD. Os processos de retenção e eluição também foram avaliados por microscopia de força atômica (AFM).Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPESporUniversidade Federal de Santa MariaCentro de Ciências Naturais e ExatasPrograma de Pós-Graduação em QuímicaUFSMBrasilQuímicaAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessHPAsCAPExtraçãoAdsorçãoPAHsAdsorptionAPCExtractionCNPQ::CIENCIAS EXATAS E DA TERRA::QUIMICAEstudo de adsorção gás-sólido de hidrocarbonetos policíclicos aromáticos em diferentes adsorventesStudy of gas-solid adsorption of polycyclic aromatic hydrocarbons in different adsorbentsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisNascimento, Paulo Cícero dohttp://lattes.cnpq.br/7151513617218161Carvalho, Leandro Machado deJost, Cristiane Luisahttp://lattes.cnpq.br/5458637349902153Brudi, Letícia Callegaro1006000000006006006006006002042fb16-c273-4428-8d59-fe233e346cbb2b6a9dbb-2705-4e0e-aba7-f6859504172719c1326f-8b95-43f2-9615-b84a964868dea3d52216-e1c2-4d8d-a94d-02e526fbbdd3reponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALDIS_PPGQUÍMICA_2021_BRUDI_LETÍCIA.pdfDIS_PPGQUÍMICA_2021_BRUDI_LETÍCIA.pdfDissertação de mestradoapplication/pdf3502494http://repositorio.ufsm.br/bitstream/1/23940/1/DIS_PPGQU%c3%8dMICA_2021_BRUDI_LET%c3%8dCIA.pdfffc99c68844c79a09f25ac173cf15bddMD51LICENSElicense.txtlicense.txttext/plain; charset=utf-81956http://repositorio.ufsm.br/bitstream/1/23940/3/license.txt2f0571ecee68693bd5cd3f17c1e075dfMD53CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml; charset=utf-8805http://repositorio.ufsm.br/bitstream/1/23940/2/license_rdf4460e5956bc1d1639be9ae6146a50347MD521/239402022-03-25 12:39:59.349oai:repositorio.ufsm.br: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ório Institucionalhttp://repositorio.ufsm.br/PUBhttp://repositorio.ufsm.br/oai/requestopendoar:39132022-03-25T15:39:59Manancial - Repositório Digital da UFSM - Universidade Federal de Santa Maria (UFSM)false

Through extraction tests in aqueous solution at 50 ºC, 100% acenaphthene, 87,30% anthracene and 86,23% fluoranthene were emitted. Regarding the emissions of APC samples at 130 ºC, a total of 32,94 mg Kg-1 of total PAHs from the REGAP sample was obtained, which was selected as a representative sample for adsorption studies; 3,37, 3,64 and 1,46 mg Kg-1 of total PAHs of the AMP, REFAP and LUBNOR samples, respectively. Through tests of the evaluation of the retention capacity using three different masses, it was observed in aqueous solution that the, PUF (adsorption yields of 100%) and XAD-2 (adsorption yields>90%) showed the greater retention capacity for PAHs, followed by HDPE (adsorption yields 75-90%). For Si, EVA and GAC, the adsorption yields depended strongly on the PAHs. Alternatively, for the asphalts samples, the adsorption yields decreased for all the evaluated PAHs, showing that the asphalt matrix had the strong influence on the adsorption process, with the total PAHs being 47,20% for PUF, 46,80% for XAD-2, 29,90% for GAC, 27,30% for Si and 19,80% for HDPE.
