Abstract

So far, the handling of dye pollution remains a challenge. One of the promising methods to reduce the dyes content from such waste is adsorption. The purpose of this study is to examine the suitability of kinetic models and to determine the removal capacity of acid blue 29 adsorptions onto activated carbon. Two mathematical models were developed to evaluate the adsorption kinetics. The first model only took into account the convective mass transfer of the dyestuff to the surface of the adsorbent, while the second model also took into account the diffusion of the dyes in the adsorbent pore. The result showed that the adsorption process followed the Langmuir equilibrium and the kinetic fits to the second model in which the adsorption rate is controlled by convection mass transfer in the liquid phase as well as the intra-particle molecular diffusion that occurs in the pore. The dye removal capacity inversely proportional to the dye concentration and reaches 86.6% when the initial dye concentration is 75 ppm.
