Résumé : |
The presence of color due to dyes in the effluents from leather industry is a major concern in today's eco-sensitive world. In this present study, the removal of three most commonly used dyes in leather industry, viz. acid, direct and metal complex dye, by adsorption onto calcium alginate beads has been studied in dynamic-batch mode. The effect of initial dye concentration, alginate quantity, size of the beads, pH and temperature on dye removal was studied for batch conditions. Experiments with commercial tannery dye effluents have also been carried out and the results indicate the potential of calcium alginate beads as effective adsorbents for removal of dyes from commercial tannery effluent. Desorption studies were carried out, which indicate the reuse potential of the alginate beads. The measured adsorption kinetics was well described by a pseudo-second order kinetic model. |
