Fixed Bed Modelling Column Adsorption Studies by Activated Carbon for Removal of Fluoride

Abstract

The fluoride removal from aqueous solution was investigated utilising Copper Pod adsorption in a fixedbed column. 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, andequilibrium fluoride uptake. With a lower flow velocity and a higher bed height, the percentage of fluorideremoved increased. At a flow rate of 5 ml/min, a bed height of 10 cm, and an initial fluoride concentrationof 5 ppm, a maximum bed capacity of 6.5 mg was achieved. The Three well-known models were used to fitdata from column studies known column models. The Yoon-Nelson model, the Thomas model, and theAdams-Bohart model. The experimental data and theoretical results remained in good accord. The studydiscovered that activated carbon can be used in a fixed bed column to remove fluoride.
