ADSORPTION KINETICS FOR THE REMOVAL OF METHYLENE BLUE AND METHYL ORANGE BY USING SUPER SAND
This study investigated the preparation of super sand substance and used it as an effective adsorbent for the removal of two different dyes methylene blue (basic) and methyl orange (acidic). The initial concentration range of dyes that were used in the adsorption process was (50−200) ppm with a temperature range (20−35) °C, the surface characteristics of graphite, graphene oxide, and coated sand were investigated by AFM test. Three adsorption kinetics models were applied to the experimental data in this study, pseudo−first order, pseudo−second order, and interparticle diffusion model. The result was showed that the experimental data corresponded with pseudo−second order kinetic model with confidence level R2= 0.99.
