Resumo: A comparison was made of ability of four ion exchange resins to remove sulfur dioxide, iron and potassium from sulfited musts. The resins used were Lewatit S 100 and MP 62 and Amberlite IR-120 and IR-45. The Lewatit MP 62 resin proved unsuitable for this purpose because it decolorized the must. Amberlite IR-120 and IR-45, removed 62-92% of the iron, 80-93% of the potassium, 50-59% of the free sulfur dioxide and 27-41% of the total sulfur dioxide without affecting the colour.

As resinas Lewatit S 100 e MP 62 revelaram-se impróprias para esta finalidade, por tirarem quase completamente a cor do mosto. Resultaram apropriadas as resinas Amberlite IR-120 e IR-45, que eliminaram 62-92% do ferro, 80-93% do potássio, 50-59% do anidrido sulfuroso livre, e 27-41% do anidrido sulfuroso total, sem influir sensivelmente sobre a cor dos mostos sulfitados.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPezzi, Germano MansuetoFenocchio, Paolo2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/17111Pesquisa Agropecuaria Brasileira; v.10, n.11, 1975: Série Agronomia; 43-45Pesquisa Agropecuária Brasileira; v.10, n.11, 1975: Série Agronomia; 43-451678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/17111/11428info:eu-repo/semantics/openAccess2014-04-15T19:01:04Zoai:ojs.seer.sct.embrapa.br:article/17111Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:01:04Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
