Abstract

The present work evaluated the simultaneous adsorption of the metallic ions Cd(II), Cu(II) and Cr(VI) onto bamboo activated carbon. The main and interactive factors studied were determined as the initial concentration of metallic ions, pH, and contact time, by using a factorial design. The analysis of variance (ANOVA) was applied in the factorial design and the statistics data showed adequate models. The kinetic model of pseudo-second-order fitted better for both single and simultaneous adsorption. The adsorption of Cr(VI) was positively improved by the presence of other ions in solution, while the adsorption of Cd(II) was repressed.
