Resumo: | The study accomplished to analyze, identify and quantify 2,4-dichlorophenol employing high efficiency chromatography with a previously validated analytical methodology. The validation was made by using some analytical parameters: linearity, precision, accuracy, quantification limit (LOQ) and detection limit (LOD). The analytical curve was linear for the studied range of concentration (10 up to 100 mg.L-1) presenting a linear regression coefficient (R2) above 0,99. Regarding the methodology accuracy, a repeatability analysis was performed by observing a coefficient of variance (CV) below 20% for each of the concentrations used. The LOD and LOQ were adequate for the analyzed compound, showing the values of 1.42 mg.L-1 and 4.30 mg.L-1, respectively. The tests to verify the accuracy, by the recovery method provided values above 79%, thus resulting in specific, sensitive, precise, linear and accurate methodology in the studied concentration range. In the advanced oxidative process UV/H2O2, the compound was degraded to 88.04% under the following experimental conditions: [H2O2] = 1016.0 mg∙L-1 in 120 minutes. Therefore, it can be affirmed that the treatment employed can be used as an alternative for industrial effluent treatment with phenolic compounds. |

FentonResumoO presente estudo analisou, identificou e quantificou o 2,4-diclorofenol via cromatografia líquida de alta eficiência, através de metodo-logia analítica previamente validada. A validação foi realizada utilizando os seguintes parâmetros analíticos: linearidade, precisão, exa-tidão, limite de quantificação (LQ) e limite de detecção (LD). A curva analítica mostrou-se linear na faixa estudada (10 a 100 mg.L-1) e com coeficiente de regressão linear (R2) superior a 0,99. Quanto à precisão da metodologia, empregou-se a análise da repetibilidade observando-se um coeficiente de variância (CV) abaixo de 20%, para cada uma das concentrações empregadas. Os LD e LQ foram adequados para o composto analisado, apresentando os seguintes valores 1,42 mg.L-1 e 4,30 mg.L-1, respectivamente. Os ensaios para verificação da exatidão, pelo método de recuperação, forneceram valores acima de 79%, resultando assim numa metodologia específica, sensível, precisa, linear e exata na faixa da concentração estudada. No processo oxidativo avançado (UV/H2O2), obteve-se uma degradação do composto analisado em até 88,04%, nas seguintes condições experimentais: [H2O2] = 1016,0 mg∙L-1; num período de 120 minutos. Desse modo, pode-se afirmar que o tratamento empregado pode ser utilizado como alternativa para tratamentos de efluentes industriais.Universidade Federal de Santa Maria2017-12-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/reget/article/view/2776610.5902/2236117027766Revista Eletrônica em Gestão, Educação e Tecnologia Ambiental; REGET, V. 21, N. 2, MAY-AUG., 2017; 147-157Revista Eletrônica em Gestão, Educação e Tecnologia Ambiental; REGET, V. 21, N. 2, MAIO-AGO., 2017; 147-1572236-11702236-1170reponame:Revista Eletrônica em Gestão Educação e Tecnologia Ambiental (REGET)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMenghttps://periodicos.ufsm.br/reget/article/view/27766/pdfCopyright (c) 2017 Electronic Journal of Management, Education and Environmental Technology (REGET)http://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccessZaidan, Léa Elias Mendes CarneiroPinheiro, Rannuzya BrandãoSantana, Rayany Magali da RochaCharamba, Lívia Vieira CarliniNapoleão, Daniella CarlaSilva, Valdinete Lins da2022-08-09T19:12:01Zoai:ojs.pkp.sfu.ca:article/27766Revistahttps://periodicos.ufsm.br/regetPUBhttps://periodicos.ufsm.br/reget/oaimarcelobdarosa@gmail.com||reget.ufsm@gmail.com2236-11702236-1170opendoar:2022-08-09T19:12:01Revista Eletrônica em Gestão Educação e Tecnologia Ambiental (REGET) - Universidade Federal de Santa Maria (UFSM)false |
