Abstract
Titan Yellow and Brilliant Green dyes were adsorbing to cement kiln dust (CKD) in this work by adjusting factors including contact time, dye concentration, adsorbent dose, pH, and different temperatures at (25, 35, 45, and 55 °C) and isotherms of adsorption. Freundlich, Langmuir, and Temkin adsorption isotherm equations were all examined. Between the Langmuir and Temkin isotherms, the equilibrium adsorption data were fitted Thermodynamic parameters ΔG, ΔH, and ΔS were calculated and the results indicated that the adsorption process on CKD was exothermic and non-spontaneous in Brilliant dye, but endothermic and spontaneous in Titan Yellow. It was also observed that adsorption was height at pH=2 for Titan dye and height at pH=8 for Brilliant dye.
