Resumo: | This work aimed to use Multiple Walls Nanotubes (MWNT) in order to synthesize a nanofilter to remove water contaminants and to test the nanofilter manufactured in removing Benzothiophene and pesticides present in water. The study was conducted in two stages. In the first step the nanofilter was developed and characterized. To develop the filter, the following materials were used: Chitosan, Polyethylene Glycol 6000 K, Sodium Hydroxide (NaOH), Sodium Dodecyl Sulphate (SDS), Acetic Acid Glacial and MWNT. To characterize the filter was performed: Scanning Electron Microscopy (SEM), Raman spectroscopy, the method of Brunauer, Emmett and Teller (BET) method Barrett, Joyner and Halenda (BJH) and permeate flow. In the second step, removal efficiency of benzothiophene and pesticides by the nanofilter was tested. For this experimental activity, it was split into two steps: filtering with benzothiophene and other pesticides. For filtering with benzothiophene, it was prepared a solution with a concentration of 0.79 ± 0.02 mmol in triplicate, where 5 samples were filtered with the same concentration of 3 similar nanofilters. For the filtering of pesticides, it was prepared one stock solution of 10.0 mL (1000.0 mg L-1) Imazapic, Imazethapyr, Imidacloprid, Ethyl Pirazolsulfuron). For pesticide analysis, it was used the Ultra Efficiency Liquid Chromatography coupled to Mass Spectrometry in series (UHPLC-MS / MS). The chromatographic conditions were established by LARP-UFSM. From the results obtained on the characterization, it can be said that the filter is characterized by low permeability and average pore radius of 15 A0. Carbon nanotubes are maintained after the manufacturing process and nanofilter may be used for removal of contaminants in water. As for the results of efficiency, nanofilter remove benzothiophene present in water with high efficiency. In addition, the nanofilter removes pesticides in water even at concentrations 10 times higher than those found in natural environment. |

O estudo foi realizado em dois capítulos. No primeiro capitulo foi desenvolvido e caracterizado o nanofiltro. Para desenvolver o nanofiltro, foram utilizados os seguintes materiais: Quitosana, Polietileno Glicol 6000 K, Hidróxido de Sódio (NaOH), Dodecil Sulfato de Sódio (SDS), Ácido Acético Glacial e NTCPM. Em Sua caracterização foram realizados as seguintes análises: Microscopia Eletrônica de Varredura (MEV), Espectroscopia Raman, método de Brunauer, Emmett e Teller (BET), método de Barrett, Joyner e Halenda (BJH) e Fluxo Permeado. No segundo capítulo, a eficiência na remoção de Benzotiofeno e agrotóxicos pelo nanofiltro foi testada. Para isto, a atividade experimental foi dividida em duas etapas: uma filtragem com Benzotiofeno e outra filtragem com agrotóxicos. Para filtragem com benzotiofeno, foi preparada uma solução com concentração de 0,79 ± 0,02 mmol em triplicata, onde 5 amostras com mesma concentração foram filtradas por 3 nanofiltros semelhantes. Para a filtragem dos agrotóxicos, foi preparada uma solução 10,0 mL da solução estoque 1000,0 mg L-1 de Imazapique, Imazetapir, Imidacloprido, Pirazolsulfuron Etílico. Para análise dos agrotóxicos foi utilizado a Cromatografia Líquida de Ultra Eficiência acoplada à Espectrometria de Massas em série (UHPLC-MS/MS). As condições cromatográficas foram estabelecidas pelo LARP-UFSM. A partir dos resultados obtidos, sobre a caracterização, pode-se afirmar que o filtro se caracteriza por baixa permeabilidade e raio médio dos poros com 15 Ao. Os nanotubos de carbono são mantidos após processo de fabricação e o nanofiltro poderia ser usado para remoção de contaminantes na água. Já para os resultados de eficiência, o nanofiltro remove o Benzotiofeno presente em água com alta eficiência. Além disso, o nanofiltro remove agrotóxicos em água mesmo com concentrações 10 vezes acima da encontrada em ambiente natural.Coordenação de Aperfeiçoamento de Pessoal de Nível Superiorapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em Engenharia AgrícolaUFSMBREngenharia AgrícolaBenzotiofenoAgrotóxicosFiltragemBenzothiophenePesticidesFilteringCNPQ::CIENCIAS AGRARIAS::ENGENHARIA AGRICOLASíntese e aplicação de nanofiltro contendo nanotubos de carbono na retenção de contaminantes em águaSynthesis and application of carbon nanotubes nanofilter on retention contaminants in waterinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisSwarowsky, Alexandrehttp://lattes.cnpq.br/9525157123018041Mazutti, Marcio Antoniohttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4770663T7Mortari, Sergio Robertohttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4721640J6http://lattes.cnpq.br/2626521926350612Nora, Robson Dalla50030000000840050030050050002d8faa1-0984-4fdc-9b71-f20c97089548b232e5ab-9afc-4e91-abe5-6ca0f36cfd7b67e239f9-31ad-4d6b-9c76-bea8273292993c621a6d-38be-4e61-b644-40b0cc92afcbinfo:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALDALLA NORA, ROBSON.pdfapplication/pdf1138804http://repositorio.ufsm.br/bitstream/1/7607/1/DALLA%20NORA%2c%20ROBSON.pdf480db40b6ad7d282197514abced4bf02MD51TEXTDALLA NORA, ROBSON.pdf.txtDALLA NORA, ROBSON.pdf.txtExtracted texttext/plain79757http://repositorio.ufsm.br/bitstream/1/7607/2/DALLA%20NORA%2c%20ROBSON.pdf.txtbc6ac0b8769eae92e004254883220559MD52THUMBNAILDALLA NORA, ROBSON.pdf.jpgDALLA NORA, ROBSON.pdf.jpgIM Thumbnailimage/jpeg5107http://repositorio.ufsm.br/bitstream/1/7607/3/DALLA%20NORA%2c%20ROBSON.pdf.jpgebbd6300fa7661608b8c910514bdebe9MD531/76072022-01-05 09:21:02.609oai:repositorio.ufsm.br:1/7607Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2022-01-05T12:21:02Biblioteca Digital de Teses e Dissertações do UFSM - Universidade Federal de Santa Maria (UFSM)false |
