Resumo: Environmental pollution is a worldwide concern, especially pollution of water bodies. To measure the level of pollution, environmental legislation uses parameters as indicators of quality. Effluents from wash stations and mechanical workshops have a high polluting power due to the amount of oil coming from automobile parts and motors. Gravimetry is the official method for Rio Grande do Sul, according to the State Foundation for Environmental Protection Henrique Luiz Roessler (Fepam). However, a method requires relatively more time and more steps than in a spectrophotometric analysis. Therefore, the present study aimed to develop a spectrophotometric methodology for the analysis of oils and greases. The samples from mechanical workshops and washing stations were collected by a laboratory accredited by the Ministry of Agriculture, Farming and Supply (MAPA) and Metrology institute (Inmetro) from a city located in Rio Grande do Sul. The samples were submitted to analysis by the official method and the results were compared to the proposed method. The results showed that the recovery tests were within the accepted range and showed to be linear.  In this way, it presents a positive perspective to be used as an alternative method with less analysis time.

Para medir o nível de poluição, a legislação ambiental utiliza parâmetros como indicadores da qualidade. Efluentes de postos de lavagens de carros e de oficinas mecânicas possuem alto poder poluidor devido a quantidade de óleo proveniente de peças e motores de automóveis. O método oficial para o Rio Grande do Sul, em conformidade com a Fundação Estadual de Proteção Ambiental Henrique Luiz Roessler (Fepam), é por gravimetria. Porém, é um método que demanda relativamente mais tempo e mais etapas do que em uma análise espectrofotométrica. Portanto, o presente estudo teve por objetivo o desenvolvimento de uma metodologia por espectrofotometria para análise de óleos e graxas. As amostras provenientes de oficinas mecânicas e postos de lavagem de carros foram coletadas por um laboratório credenciado pelo Ministério da Agricultura, Agropecuária e Abastecimento (MAPA) e Inmetro, de um município situado no Rio Grande do Sul. As amostras foram submetidas à análise pelo método oficial e comparou-se os resultados com o método proposto. Os resultados demonstraram que os testes de recuperação se situaram dentro da faixa aceita e demonstraram ser lineares. Dessa maneira, apresenta uma perspectiva positiva para ser utilizado como método alternativo com menor tempo de análise.Universidade Federal do AmapáKich, MarinaBöckel, Wolmir José2017-10-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.unifap.br/index.php/estacao/article/view/350410.18468/estcien.2017v7n3.p61-69Estação Científica (UNIFAP); v. 7, n. 3 (2017); 61-69Estação Científica (UNIFAP); v. 7, n. 3 (2017); 61-692179-1902reponame:Estação Científica (UNIFAP)instname:Universidade Federal do Amapá (UNIFAP)instacron:UNIFAPporhttps://periodicos.unifap.br/index.php/estacao/article/view/3504/marinav7n3.pdfDireitos autorais 2017 Estação Científica (UNIFAP)http://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess2017-12-19T17:37:43Zoai:ojs.pkp.sfu.ca:article/3504Revistahttps://periodicos.unifap.br/index.php/estacaoONGhttps://periodicos.unifap.br/index.php/estacao/oai||fernandogentry@hotmail.com2179-19022179-1902opendoar:2017-12-19T17:37:43Estação Científica (UNIFAP) - Universidade Federal do Amapá (UNIFAP)false
