Fluoride is an essential ion for human health, but both its deficiency and excess intake can lead to health problems. The primary source of fluoride for humans is drinking water, and in many regions, excessive fluoride in water poses significant health risks, such as dental and skeletal fluorosis. Effective removal of fluoride from water is therefore critical, particularly in areas where naturally occurring fluoride levels exceed safe limits. Aim of this study was to remove fluoride ions from aqueous solutions using activated carbon (AC). Pine needles and pine cones were selected as the carbon precursors due to their availability and low cost. These materials were chemically activated using zinc chloride (ZnCl₂) at various impregnation ratios (1:1, 1:2, and 1:3) and carbonization temperatures (500 ℃, 600 ℃, and 700 ℃).The resulting activated carbon was characterized using different analytical techniques, ensuring its suitability for fluoride adsorption. A synthesized fluoride solution, prepared using sodium fluoride (NaF), was treated with the AC, and fluoride concentrations were measured using the SPADNS method. The adsorption data were analysed with various isotherm models, and it was found that the Freundlich model provided the best fit for the equilibrium data. The maximum surface areas obtained for the activated carbons were 750 m2/g for the pine needle-derived carbon and 498 m2/g for the pine cone-derived carbon, both produced at a 1:3 impregnation ratio and carbonized at 600 ℃. Ultimately, the study demonstrated that pine needles and pine cones are viable low-cost precursors for producing effective activated carbon, offering an eco-friendly and efficient solution for fluoride removal from water.
