Abstract
This experiment was about the ability of waste alumina to remove fluoride that exist in industrial wastewater. The effects of the diameter and dosage of alumina, pH, adsorption time and the initial fluorine concentration on the adsorption properties were studied. The results showed that if the dosage of alumina constant, the adsorption capacity of alumina increases with smaller the diameter and higher the fluoride concentration of waste water. And the highest removal capacities were achieved at pH range 4 to 6 while the dosage of alumina was 5%o and adsorption time was 30 min. The adsorption isotherm of alumina at different temperatures was made and they obey Freundlich Equation that had already be proved. Through this experiment we got the conclusion that the highest removal capacities were achieved while the diameter was between 1. 0 to 3. 2 mm and the dosage of alumina was 5%o, the pH range 4 to 6, adsorption time was 30min and temperature was 20 ℃.关键词
