摘要：
The adsorption isotherms of fluoride from an aqueous solution on plain and aluminum-impregnated activated carbons were measured in this study. The impregnated carbon was prepared by impregnation with an aluminum nitrate solution at a fixed pH, followed by calcination under nitrogen at temperatures above 300 degrees C. The adsorption of fluoride on impregnated carbon was shown to be dependent upon both the pH of the impregnating solution and the temperature of calcination. Impregnated carbon was shown to have a fluoride adsorption capacity of 3 to 5 times that of plain activated carbon. (C) 1999 Elsevier Science Ltd. All rights reserved.
