Resumo: | This work investigated the biosorption of chromium (III) and nickel (II) present in the effluent of a galvanoplasty plant using the pre-treated biomass of Sargassum filipendula seaweed. The column operation conditions were 8 g of biosorbent mass, 3.85 pH for the feed effluent, 30ºC temperature, 6 mL min.-1 flow rate, 7.12 meq L-1 initial chromium concentration and 3.66 meq L-1 initial nickel concentration. A mathematical model was used to represent the dynamics of biosorption of the metals in a fixed-bed column. The Langmuir multicomponent isotherm model (qm = 2.78 meq g-1, bCr = 0.85 L meq-1, bNi = 0.08 L meq-1) was used to represent the equilibrium data of the column and to simulate the biosorption dynamics of the ions. The simulation results showed that the mathematical model described satisfactory the complex binary biosorption of chromium and nickel in the effluent. |

As condições de operação da coluna foram: massa de biossorvente de 8 g, pH do efluente de alimentação 3,85, temperatura de 30ºC, vazão de 6 mL min.-1 e concentrações iniciais de alimentação (cromo+níquel) de 7,12 e 3,66 meq L-1. Foi empregado um modelo matemático para representar a dinâmica da biossorção em coluna de leito fixo. O modelo da isoterma multicomponente de Langmuir (qm= 2,78 meq g-1, bCr = 0,85 L meq-1, bNi = 0,08 L meq-1) foi utilizado para representar os dados de equilíbrio da coluna e para simular a dinâmica de biossorção dos íons. Os resultados da simulação demonstraram que o modelo matemático empregado foi capaz de descrever satisfatoriamente a complexa dinâmica de biossorção dos íons presentes no efluente.Universidade Estadual De Maringá2009-06-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionbiosorption; fixed bed; seaweed; binary system; modeling; effluent.application/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/86410.4025/actascitechnol.v31i2.864Acta Scientiarum.

A mathematical model was used to represent the dynamics of biosorption of the metals in a fixed-bed column. The Langmuir multicomponent isotherm model (qm = 2.78 meq g-1, bCr = 0.85 L meq-1, bNi = 0.08 L meq-1) was used to represent the equilibrium data of the column and to simulate the biosorption dynamics of the ions.
