Modeling of Fixed Bed Column Adsorption Studies Fluoride by Phoenix Dactylifera (Date Palm) Seeds provide Activated Carbon

Abstract

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.
