Resumo: | Polycyclic aromatic hydrocarbons, nitrogen and oxygen (Nitro-PAHs and Oxy-PAHs) compose the class of compounds where a hetero atom of nitrogen and oxygen, respectively, is present in the constitution of the HPA. The inclusion of a heteroatom leads to increased mobility and increased toxicological potential. In this work were investigated adsorbent materials for removal of Nitro-PAH and Oxy-PAH from aqueous solutions. For this purpose, activated carbon (AC), polyurethane foam (PUF), quartz fiber (QF), high density polyethylene (PEHD), polytetrafluoroethylene Teflon (PTFE), Amberlite XAD-2 (XAD-2) and silica gel (Si), were evaluated as potential solid substrates, as well as its use as an alternative to XAD -2 for making personal samplers type lapel. Quinoline, 1-nitronaphthalene, Acridine, Phenazine, 2-nitrofluorene, 9-nitroanthracene and 1-nitropyrene were chosen as representatives of the class of compounds Nitro-PAHs. 2-naphthol, 2-hydroxyfluorene, Phenanthrene-9-carboxaldehyde, 9,10-anthraquinone, and 1-hydroxypyrene were chosen as representatives of the class of compounds Oxy-PAHs. The results were obtained by batch tests. For Nitro-PAHs, the adsorbents with the highest removal rates were: XAD-2 (100% removal on XAD-2, except for Quinoline - 80%) and activated carbon (around 90% for all reviews compounds). For Oxy-PAHs, the highest removal rates were provided by adsorbents: polyurethane foam and activated carbon, both with rates higher than 90% of removal. Due to the low solubility of the compounds, the presence of a co-solvent is required. The lowest temperature (20 ⁰C) favored the adsorption of the compounds. In general, both (Nitro-PAHs and Oxy-PAHs) classes have their removal influenced by increasing the concentration of the solute in solution. |

A inserção do heteroátomo acarreta numa maior mobilidade e aumento do potencial toxicológico. Neste trabalho foram investigados materiais adsorventes para a remoção de Nitro-HPAs e Oxi-HPAs a partir de soluções aquosas. Para isto, carvão ativado, espuma de poliuretano, fibra de quartzo, polietileno de alta densidade, politetrafluoretileno (teflon), Amberlite XAD-2 e sílica gel, foram avaliados como possíveis substratos sólidos. Quinolina, 1-nitronaftaleno, Acridina, Fenazina, 2-nitrofluoreno, 9-nitroantraceno e 1-nitropireno foram escolhidos como representantes à classe de compostos Nitro-HPAs. 2-naftol, 2-hidroxifluoreno, Fenantreno-9-carboxaldeído, 9,10-antraquinona e 1-hidroxipireno foram escolhidos como representantes à classe de compostos Oxi-HPAs. Os resultados foram obtidos através de ensaios em batelada. Para os Nitro-HPAs estudados, os adsorventes que apresentaram as maiores taxas de remoção foram: XAD-2 (100% de remoção em XAD-2, exceto pra Quinolina 80%) e carvão ativado (em torno de 90% para todos os compostos avaliados). Para os Oxi-HPAs estudados, as maiores taxas de remoção foram proporcionadas pelos adsorventes: espuma de poliuretano e carvão ativado, ambos com taxas de remoção superiores a 90%. Devido à baixa solubilidade dos compostos, a presença de um co-solvente se faz necessária. A temperatura mais baixa (20 ⁰C) favoreceu a adsorção dos compostos. De modo geral, ambas as classes (Nitro-HPAs e Oxi-HPAs) tem sua remoção influenciada pelo aumento da concentração do soluto em solução.application/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em QuímicaUFSMBRQuímicaNitro-HPAOxi-HPARemoçãoAdsorçãoNitro-PAHsOxy-PAHRemovalAdsorptionCNPQ::CIENCIAS EXATAS E DA TERRA::QUIMICAAvaliação de adsorventes sólidos para a remoção de derivados de HPAs em soluçãoEvaluation of solid adsorbents for removal of derivatives PAHs in solutioninfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisNascimento, Paulo Cícero dohttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4788664D2Dias, Daianehttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4735174A3Rosa, Marcelo Barcellos dahttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4792062P5http://lattes.cnpq.br/3625853714790767Colim, Alexsandro Nunes1006000000004005003003003002042fb16-c273-4428-8d59-fe233e346cbb07dba217-dace-45a3-9c6b-288014b3a2c2f31cd92f-1160-4b34-b56a-8d32d2c04171d444ab73-8f6f-4cef-9d68-abe0875d35f8info:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALCOLIM, ALEXSANDRO NUNES.pdfDissertação de Mestradoapplication/pdf2603959http://repositorio.ufsm.br/bitstream/1/10565/1/COLIM%2c%20ALEXSANDRO%20NUNES.pdf64e545359e3aadaf93674e2768174941MD51TEXTCOLIM, ALEXSANDRO NUNES.pdf.txtCOLIM, ALEXSANDRO NUNES.pdf.txtExtracted texttext/plain133312http://repositorio.ufsm.br/bitstream/1/10565/2/COLIM%2c%20ALEXSANDRO%20NUNES.pdf.txtdf7ca33a0da78bb287e305aac59dba59MD52THUMBNAILCOLIM, ALEXSANDRO NUNES.pdf.jpgCOLIM, ALEXSANDRO NUNES.pdf.jpgIM Thumbnailimage/jpeg4639http://repositorio.ufsm.br/bitstream/1/10565/3/COLIM%2c%20ALEXSANDRO%20NUNES.pdf.jpga2981671add8e2ed3056b47d67c6d882MD531/105652018-01-26 02:32:22.654oai:repositorio.ufsm.br:1/10565Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2018-01-26T04:32:22Biblioteca Digital de Teses e Dissertações do UFSM - Universidade Federal de Santa Maria (UFSM)false |
