Resumo: The applicability of biochar in water treatment has been gaining interest due to its sustainability and low production cost. Thus, this work proposes the use of Biochar from Serra Gaúcha (BSG) as an adsorption element for zinc (Zn) and nickel (Ni) from industrial effluent. A load of metals present in this effluent originates essentially in the pretreatment and E-coat painting process of a metalworking company in the northwest of the state of Rio Grande do Sul – Brazil. The BSG adsorbent was characterized by Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR), Differential Scanning Calorimetry (DSC), and thermogravimetric analysis (TGA), techniques which showed the feasibility of using the adsorbent, such as the presence of irregular cavities, surface area and pore volume were determined by the BET and BJH method, adsorption capacity of cationic species and thermal stability. In batch tests, better performance was obtained at alkaline pH. Adsorption kinetics indicated that equilibrium was reached after approximately 60 minutes of adsorption. Both pseudo-first and pseudo-second-order kinetic models fit the experimental data satisfactorily. Adsorption isotherms showed linear behavior between concentration and adsorption capacity; therefore, Henry's model was chosen to represent the fit of the experimental data. [...]

[...]O uso do biochar no tratamento de água vem ganhando interesse devido a sua sustentabilidade e baixo custo de produção. Desse modo, esse trabalho propõe a utilização do Biochar proveniente da Serra Gaúcha (BSG) como elemento de adsorção de zinco (Zn) e níquel (Ni) de um efluente industrial. A carga de metais presentes nesse efluente é essencialmente originada no processo de pré-tratamento e pintura E-coat de uma empresa do ramo metalmecânico do noroeste do estado do Rio grande do Sul – Brasil. O adsorvente BSG foi caracterizado por Microscopia Eletrônica de Varredura (MEV), Difração de Raio-X (DRX), Espectroscopia no Infravermelho por Transformada de Fourier (FT-IR), Calorimetria de Varredura Diferencial (DSC), análise Termogravimétrica (TGA), técnicas as quais mostraram a viabilidade de utilização do adsorvente, como a presença de cavidades irregulares, a área de superfície e volume do poro foram determinadas pelo método de BET e BJH, capacidade de adsorção de espécies catiônicas e estabilidade térmica. Nos ensaios em batelada, obteve-se melhor desempenho em pH alcalino. A cinética de adsorção indicou que o equilíbrio foi atingido em aproximadamente 60 minutos de adsorção. Ambos os modelos cinéticos de pseudo primeira e de pseudo segunda ordem, se ajustaram aos dados experimentais de maneira satisfatória. As isotermas de adsorção apresentaram comportamento linear entre a concentração e a capacidade de adsorção; sendo assim, o modelo de Henry foi escolhido para representar o ajuste dos dados experimentais. Os valores de energia de Gibbs (−42 −¹ < ∆ 0 < −27 −¹ ), de entropia (∆ 0 = 0,26 −¹ −¹ ) e de entalpia (∆ 0 = 42,43 −¹ ) indicaram que o processo é espontâneo e endotérmico, o que mostra que a remoção de níquel e de zinco é favorecida pelo aumento da temperatura de adsorção. Por fim, os ensaios em leito fixo para a adsorção do níquel encontraram condições ótimas uma altura de leito, concentração inicial de níquel e vazão. O adsorvente (BSG) se mostrou promissor para remoção dos metais, atendendo as condições da licença de operação da industria de 0,2 mg L-1 de níquel e 2,0 mg L-1 de zinco.porUniversidade Federal de Santa MariaCentro de TecnologiaPrograma de Pós-Graduação em Engenharia QuímicaUFSMBrasilEngenharia QuímicaAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessBiocarvãoNíquelZincoIsotermaCinéticaLeito fixoBiocharNickelZincFixed bedKineticsIsothermCNPQ::ENGENHARIAS::ENGENHARIA QUIMICAPolimento de efluentes industriais através da adsorção com biochar proveniente de resíduos da vinificaçãoPolishing of industrial effluents through adsorption with biochar from vinification residuesinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisDotto, Guilherme Luizhttp://lattes.cnpq.br/5412544199323879Ketzer, FelipeMallmann, Evandro StoffelsCadaval Junior, Tito Roberto Sant’AnnaXCarvalho, Fernando Lima300600000006600cb4c4429-649d-4998-a6b3-cfcf481ab6b9c09ffe02-84e7-4ccc-a57f-f36d78833baaa8d46cff-b6b1-4b43-b7a6-e70af1d7da02d6b0623c-d90d-4a2a-bb93-ddfb0cd4b2a75e4e0462-66a6-4d0c-bbdd-d70a23976a3areponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMLICENSElicense.txtlicense.txttext/plain; charset=utf-81956http://repositorio.ufsm.br/bitstream/1/28778/3/license.txt2f0571ecee68693bd5cd3f17c1e075dfMD53CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml; charset=utf-8805http://repositorio.ufsm.br/bitstream/1/28778/2/license_rdf4460e5956bc1d1639be9ae6146a50347MD52ORIGINALDIS_PPGEQ_2023_CARVALHO_FERNANDO.pdfDIS_PPGEQ_2023_CARVALHO_FERNANDO.pdfDissertação de Mestradoapplication/pdf2421323http://repositorio.ufsm.br/bitstream/1/28778/1/DIS_PPGEQ_2023_CARVALHO_FERNANDO.pdfe2f6737ac673e2340d0ea59e29be1bc1MD511/287782023-04-28 16:43:46.758oai:repositorio.ufsm.br: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ório Institucionalhttp://repositorio.ufsm.br/PUBhttp://repositorio.ufsm.br/oai/requestopendoar:39132023-04-28T19:43:46Manancial - Repositório Digital da UFSM - Universidade Federal de Santa Maria (UFSM)false
