This study aims to prepare an adsorptive agent from the cluster fig (Ficus racemosa) leaf biomass and its utilization for the elimination of fluoride ions from the synthetic water. A carbon material developed from Leaf biomass was impregnated with zirconium at temperature (300 ºC). Scanning electron microscopy (SEM) and Fourier transformed infrared spectroscopy (FTIR) were used to analyze the appearance of surface structure and present functional groups on its surface. Determination of zero point charge (pHzpc) of the adsorbent particles also was conducted by salt addition methods. Effect of adsorbent amount, pH of the solution, interaction time, and starting fluoride ion concentration on adsorption percentage were studied at room temperature. Under optimized conditions including 4 g/L adsorbent dose, 10 mg/L initial concentration of fluoride, and neutral pH, the maximum adsorption percentage of fluoride was found to be 84.5%. The maximum adsorption capacity of the adsorbent was obtained 2.12 mg/g. The adsorbent having good adsorption performance can be applied for the defluoridation of water. The preparation cost of the prepared adsorbent also was estimated in this study.
