The  fluoride removal from aqueous solution was investigated utilising Phoenix Dactylifera adsorption in a fixed bed column (Date Palm). The effects of flow rate, bed height, and fluoride concentration at the start were studied. Breakthrough curves were plotted after determining maximum bed capacity, % fluoride elimination, and equilibrium fluoride uptake. With a lower flow velocity and a higher bed height, the percentage of fluoride removed increased. At a flow rate of 5 ml/min, a bed height of 10 cm, and an initial fluoride concentration of 5 ppm, a maximum bed capacity of 6.5 mg was achieved. The Three well-known models were used to fit data from column studies known column models. The Yoon-Nelson model, the Thomas model, and the Adams-Bohart model. The experimental data and theoretical results remained in good accord. The study discovered that activated carbon can be used in a fixed bed column to remove fluoride.
