Application of Persimmon Tree Leaf for Dye Removal

In recent years, there is a growing interest in using low cost adsorbents. Tree leaves, wool fiber, nanoclay are available adsorbent materials. In this work, persimmon tree leaves as adsorbent can well remove neutral red dye from solutions. Nowadays dyes are present in wastewater of different industries and lead to environmental pollution. Desired amount of persimmon tree leaves in dye solutions could remove dye up to 97%. Adsorption isotherms and the thermodynamic parameters were calculated. The thermodynamic studies indicated to the adsorption reaction was a spontaneous and exothermic process. .
