Fluoride removal with varying different parameters at 303 +/- 1.6K and pH 6.5 +/- 0.2 was investigated by hydrous iron(III)-chromium(III) bimetal oxide. The kinetic and equilibrium data fitted with the pseudo-second order and Langmuir isotherm equations very well (R2=0.99-1.00), respectively. The Langmuir capacity () and free energy (EDR) of adsorption evaluated were 16.34 (+/- 0.50) mg center dot g-1 and 15.81kJ center dot mol-1, respectively. The estimated thermodynamic parameters viz. H0, G0, and S0 indicated that the reaction was endothermic but spontaneous for entropy increase. The small-scale column filtration of high fluoride (C0=7.37mg center dot L-1) water gave encouraging results.
