Resumo: Humic substances are formed through the decomposition of plants and animal tissues producing complex chemical structures. They are the main organic components of the environment, presenting the ability to complex heavy metals present in natural waters, making these chemical species less toxic than those that are not complexed. Thus, the complexing capacity associated with organic matter has a great environmental impact and can be used as an indicator of water quality. The complexing capacity and the conditional complexing constant of humic substances dissolved in natural waters were determined by voltammetric titration. Appropriate volumes of samples collected in the sub-basins of the Turvo Sujo river and São Bartolomeu stream in the Zona da Mata Mineira were titrated through successive additions of Cu(II) solution. The sub-basins cover the municipalities of Viçosa, Coimbra, Cajuri and Teixeiras and are important for this region in terms of water supply for livestock and agriculture. The values ??of complexing capacities and determined conditional complexing constants showed values ??compatible with those found in the literature for natural waters.

São os componentes orgânicos principais do meio ambiente, apresentando a habilidade de complexar metais pesados presentes em águas naturais, tornando estas espécies químicas menos tóxicas que as não complexadas. A capacidade de complexação associada com a matéria orgânica tem um grande impacto ambiental, podendo ser utilizada como um indicador da qualidade da água. Assim a capacidade de complexação e a constante de complexação condicional das substâncias húmicas dissolvidas em águas naturais foram determinadas por titulação voltamétrica. Volumes apropriados das amostras coletadas nas sub-bacias do rio Turvo Sujo e do ribeirão São Bartolomeu na Zona da Mata Mineira foram tituladas através de sucessivas adições de solução de Cu(II). As sub-bacias abrangem os municípios de Viçosa, Coimbra, Cajuri e Teixeiras e são importantes para esta região em termos de abastecimento de água para a população, pecuária e agricultura. Os valores das capacidades de complexação e das constantes de complexação condicional determinadas apresentaram valores compatíveis com aqueles encontrados na literatura para águas naturais.Universidade Federal de Viçosa - UFV2021-05-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/jcec/article/view/1217210.18540/jcecvl7iss2pp12172-01-13eThe Journal of Engineering and Exact Sciences; Vol. 7 No. 2 (2021); 12172-01-13eThe Journal of Engineering and Exact Sciences; Vol. 7 Núm. 2 (2021); 12172-01-13eThe Journal of Engineering and Exact Sciences; v. 7 n. 2 (2021); 12172-01-13e2527-1075reponame:The Journal of Engineering and Exact Sciencesinstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/jcec/article/view/12172/6648Copyright (c) 2021 The Journal of Engineering and Exact Scienceshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessDutra, Rita AparecidaReis, Efraim LázaroReis, CésarCustódio, GisleneDamasceno, Odilaine Inácio de Carvalho2021-07-05T18:18:27Zoai:ojs.periodicos.ufv.br:article/12172Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/oai2527-10752527-1075opendoar:2021-07-05T18:18:27The Journal of Engineering and Exact Sciences - Universidade Federal de Viçosa (UFV)false
