Abstract :

The adsorption kinetics of the removal of fluoride (F–) from water over lime stone slurry impregnated fly ash (LSFA) catalyst using batch mode has been investigated in the present study. BET surface area, XRF, XRD, FTIR and SEM techniques were used to characterize the physico–chemical attributes (crytallinity, determination of calcium and magnesium silicate phases, morphology) of the catalyst. Adsorption data were modelled using the Freundlich and Langmuir adsorption isotherms and followed first order kinetic equation. The present research includes assessment of a new adsorbent generation, process optimization and a cost benefit process.
