Abstract :
The red clay was used as absorbent to treat fluoride wastewater by adsorption. And the effects of liquid-solid ratios, pH and reaction time on removel of fluoride were investigated. The results shown that the removel fluoride was realizable by physical and chemical adsorption, and the physical adsorption was dominant. The liquid-solid ratios, pH and reaction time were 50g/L, 9.0 and 1.5h, respectively, while the clearance of fluoride was above 90%. Besides, the adsorption isotherm of red clay generally resembled the standard L-type isotherm.
