Abstracts

Wastewater from textile industries is often discharged into the environment, negatively impacting both aquatic and terrestrial life, as well as the aesthetic value of the surroundings. This research evaluates the activated carbon from star apple seed testa and its application in removing the cationic dye eosin red from wastewater. The Langmuir and Freundlich models were employed to evaluate the adsorption isotherms. The results indicate that adsorption efficiency increases with longer contact time and higher adsorbent doses, while it decreases with higher adsorbent concentration. Furthermore, the adsorption of eosin red dye by the activated carbon prepared from star apple seed testa follows the Freundlich isotherm model, indicating that the surface of the adsorbent is heterogeneous.
