| Abstract | ||
| The adsorption efficiency of kaolin clay by adsorption of reactive blue dye (RB13) at different parameters such as pH, dosage of adsorbent, contact time and solution temperature on the adsorption process were investigated. The experimental results show that the percentage of reactive blue removal increases with increasing the dosage of kaolin clay. Equilibrium adsorption data were analyzed by Langmuir and Freundlich isotherm of the results revealed that Langmuir isotherm fitted the experimental results. The thermodynamic parameters (ΔHo, ΔGo , and ΔSo) were also determined from the temperature dependence. The results indicate that the process of adsorption reactive blue dye was spontaneous and exothermic process . | ||
