Resumo: | In this research, different concentrations of the powder of the solid residue from the hydrodistillation of the pink pepper leaf (PRHPPL), generated in the production of its essential oil, were evaluated as an inhibitor forcarbon steel in HCl0.5 molL-1.This evaluation was performed using electrochemical impedance spectroscopy (EIS), potentiodynamic polarization, scanning vibrating electrode technique(SVET),and mass loss tests. All tests showed that the highest concentration of the inhibitor (1.77 gL-1) presentedbetter efficiency;fromicorr, this efficiency was 98 %, fromthe equivalent circuitmodelRctvalueit was 98 %and by the gravimetric test it was 86 %.Different isotherms were tested in order to better understand the adsorption process of the inhibitor molecules on the metal surface and the best fit wasfound forthe Langmuirisotherm. The morphology of the steelsurface was also analyzed by scanning electron microscopy (SEM). This study reveals that this residue obtained from the production of essential oils can be used as corrosion inhibitor inthe replacement to synthetic inhibitors. |

Esta avaliação foi realizada por meio de espectroscopia de impedância eletroquímica (EIS), polarização potenciodinâmica, técnica de varredura de eletrodo vibratório (SVET) e testes de perda de massa. Todos os testes mostraram que a maior concentração do inibidor (1,77 g L-1) apresentou melhor eficiência; do icorr, essa eficiência foi de 98%, do modelo de circuito equivalente Rct valor foi de 98% e pelo teste gravimétrico foi de 86%. Diferentes isotermas foram testadas a fim de entender melhor o processo de adsorção das moléculas inibidoras na superfície do metal e o melhor ajuste foi encontrado para a isoterma de Langmuir. A morfologia da superfície do aço também foi analisada por microscopia eletrônica de varredura (MEV). Este estudo revela que este resíduo obtido da produção de óleos essenciais pode ser utilizado como inibidor de corrosão em substituição aos inibidores sintéticos.CNPq - Conselho Nacional de Desenvolvimento Científico e TecnológicoengUniversidade Federal de Minas GeraisUFMGBrasilENG - DEPARTAMENTO DE ENGENHARIA QUÍMICAResearch, Society and DevelopmentCorrosãoInibidoresAroeira-vermelhaEquações matemáticasCorrosionNatural InhibitorsPink pepperSVETAdsorption isothermsUse of the hydrodistillation residue of the essential oil of pink pepper (Schinus terebinthifolius Raddi) in the corrosion protection of carbon steel in HCl mediumUtilização do resíduo da hidrodestilação do óleo essencial de pimenta rosa (Schinus terebinthifolius Raddi) na proteção contra corrosão de aço carbono em meio HClUsoinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://rsdjournal.org/index.php/rsd/article/view/35797Nayara Maria Santos de AlmeidaIago Magella Fernandes Costa Rossi e SilvaBrunela Pereira da SilvaFernando CottingIdalina Vieira AokiTacia Costa VelosoVera Rosa Capelossiapplication/pdfinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain; charset=utf-82042https://repositorio.ufmg.br/bitstream/1843/60748/1/License.txtfa505098d172de0bc8864fc1287ffe22MD51ORIGINALUse of the hydrodistillation residue of the essential oil of pink pepper (Schinus terebinthifolius Raddi) in the corrosion protection of carbon steel in HCl medium.pdfUse of the hydrodistillation residue of the essential oil of pink pepper (Schinus terebinthifolius Raddi) in the corrosion protection of carbon steel in HCl medium.pdfapplication/pdf727269https://repositorio.ufmg.br/bitstream/1843/60748/2/Use%20of%20the%20hydrodistillation%20residue%20of%20the%20essential%20oil%20of%20pink%20pepper%20%28Schinus%20terebinthifolius%20Raddi%29%20in%20the%20corrosion%20protection%20of%20carbon%20steel%20in%20HCl%20medium.pdf96c64e119f48ad70edb8a2c09596d480MD521843/607482023-11-09 18:42:02.917oai:repositorio.ufmg.br:1843/60748Repositório de PublicaçõesPUBhttps://repositorio.ufmg.br/oaiopendoar:2023-11-09T21:42:02Repositório Institucional da UFMG - Universidade Federal de Minas Gerais (UFMG)false |
