Abstract

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.
