Batch Comparative Adsorption Studies of Fluoride Using Activated Carbon Derived from Magnifera Indica (Mango) Seeds and Peltophorum Pterocarpum (Copper Pod) Seeds

Abstract

Activated Carbon (AC) is frequently used for purification due to its ability to remove pollutants either from air or water. Its porous structure allowed it to capture pollutants and is widely recommended for numerous applications in water and wastewater treatment. However, AC applications fields are restricted due to high costs. In this project, AC was prepared from locally available Magnifera Indica (Mango) seeds and Peltophorum Pterocarpum(Copper Pod) seeds. The removal of Fluoride from the synthetic sample by adsorption on physically activated carbon prepared from Magnifera Indica (Mango) seeds and Peltophorum Pterocarpum(Copper Pod) seeds have been carried out at room temperature 32 ± 1oC. Batch adsorption processes were conducted for the removal of Fluoride on physically activated carbon for optimum time, optimum dosage, optimum pH sorption kinetics sorption equilibrium. The optimum contact time, adsorbent dose, and pH for carbon was 35 min, 100 mg and 8.00 and 40min, 160mg and 8.50 respectively, with a fluoride removal efficiency of 78.96%, 96%, 97% and 45%, 58%, 96% respectively have been observed. Adsorption kinetics and sorption isotherm models were studied by altering different process parameters like adsorption time and dosage respectively. Langmuir, Freundlich, and Temkin isotherms are studied through this experimental data and found to be well followed.
