Resumo: Leather industries produce a great volume of effluents, and chromium is the principal agent used in the leather tanning. An alternative/additional method of treatment of this effluent is the biosorption, passive link of metals by alive or dead biomass. The purpose of this work was to verify the influence of buffer solution on chromium(III) biosorption by the seaweed Sargassum sp. biomass. The evaluation was performed by kinetic study and batch equilibrium experiments in systems with and without buffer solutions. The buffer solution used were acetic acid/sodium acetate and potassium bftalate/cloridric acid. The results showed that the systems with buffer solution needed a longer time to reach the equilibrium, the buffer solutions were not able to maintain the pH and the isotherms showed a reduction of the biomass biosorptive ability.

Um método alternativo/adicional de tratamento para este efluente é a biossorção, ligação passiva de metais por biomassa viva ou morta. O objetivo do trabalho foi verificar a influência da utilização de solução tampão sobre a biossorção do cromo(III) pela biomassa da alga marinha Sargassum sp. A avaliação foi realizada por meio de um acompanhamento cinético da biossorção, e pela obtenção de isotermas utilizando sistemas de biossorção com e sem solução tampão. As soluções tampão utilizadas foram ácido acético/acetato de sódio e biftalato de potássio/ácido clorídrico. Os resultados revelaram que os sistemas contendo solução tampão necessitavam de um tempo maior para atingir o equilíbrio; as soluções tampão não foram capazes de manter o pH no valor desejado, e as isotermas indicaram uma redução da capacidade biossortiva da biomassa.Universidade Estadual De Maringá2008-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/225110.4025/actascitechnol.v25i1.2251Acta Scientiarum.
