| Abstract The research included study the adsorption of toluidine blue O (TBO) dye on the surface of MnO2 which was used as a catalyst in several reactions especially photo reactions. Many of parameters were studied which affect the a adsorption process such as: weight of MnO2,equilibrium time,effect of pH and the type of adsorbent. MnO2 was used as a model adsorbent in the experiments. These experiments were done under room temperature and showed that the optimum wight of MnO2 was (0.6 g),equilibrium time was (90 min.) while the best adsorbent was MnO2/ZnO. Also the experiments showed that the (pH=8) was the best medium of the adsorption process while negative effects- due to acidic and basic media- were observed in the adsorption process. Adsorption isotherms and their applications were also studied such as Freundlich and Langmuir isotherms. | ||
