N2 - The aim of this study was to synthesize and evaluate low-cost, eco-friendly nanoparticles prepared from black cotton soil and Prosopis juliflora seeds for the removal of fluoride from contaminated water. The synthesized adsorbent was characterized using FTIR, XRD, and SEM, which confirmed the presence of functional groups, crystalline phases, and a porous nanoscale structure with an average crystallite size of about 16.5 nm. Batch adsorption experiments showed that the material had strong fluoride removal performance, with the best formulation achieving up to 98.9% removal for S1, 90.1% for S2, and 89.7% for S3 under optimized conditions of pH 4, 0.06 g dose, and 30 min contact time. The adsorption process followed pseudo-second-order kinetics and the Freundlich isotherm, indicating chemisorption on a heterogeneous surface. These findings demonstrate that the prepared nanoparticles are promising for sustainable defluorination of drinking water. It is recommended that future work focus on regeneration, reuse, and pilot-scale testing under real field conditions.
