Abstract

This study was conducted to determine the suitability of the observed equilibrium and kinetic model, as well as the removal of acid violet 17. The batch experimental variables include the dyes initial concentration and the ratio of the adsorbent mass to the volume of the solution. The adsorption equilibrium data were examined using three equilibrium models i.e., Linear, Freundlich, and Langmuir. The observed model is limited by two forms of the proposed kinetic model. The first model just considers the convection mass transfer of the dyes to the external surface of the adsorbent, while the second model also takes into account the solute diffusion in particles. The experiment result showed that the adsorption process follows the Langmuir correlation with the adsorption capacity of 185.19 mg/g. From this study, it was found that the adsorption is controlled by the diffusion stage inside the particle. The dyes removal reach 58%, which was achieved when 0.0015-gram adsorbent was used per ml solution. The results of this study can contribute to the design of the commercial scale adsorption process.
