Removal of fluorine ions from industrial zinc sulfate

The layered aluminumbased composite is first used to remove fluorine ions from industrial zinc sulfate solution. • The concentration of fluorine ion can be reduced to less than 20 mg/L when the temperature is 50 o C and the dosage is 30 g/L.. The adsorbent could be regenerated and keep high efficiency after several adsorptiondesorption cycles.
