Evaluation of the Efficiency of Tea Waste Powder to Remove the Safranin O dye Compared to the Activated Carbon As Adsorbent

Tea waste and active carbon manufactured from dates’ stone were used as adsorbents for removal Safranin O dye and the results were compared. Safranin O dye removal efficiency was studied by batch adsorption. The experimental results displayed that the removal efficiency of dye on the two adsorbent were greatest at high acidic solution of SO solution for tea adsorbent, while for Activated Carbon at high alkalinity for the same dye. This study shows the adsorption equilibrium isotherms were followed Freundlich and Langmuir isotherms, where safranin O dye adsorption obey Freundlich isotherm. The effect of temperature was studied and thermodynamic parameters were calculated.
