Table 2-4 XPS analysis of Tea-Al, Tea-APAM-Al before and after fluoride adsorption
• Tea-APAM-Al showed a remarkable increase from 4.02% to 15.99% in comparison to Tea-Al. • The quantity of sulfate ion could be increased with the participation of APAM among the loading progress. • Sulfate ions might be replaced by fluoride, which was consistent with the results of FTIR and adsorption experiments.
• A new F (1s) peak was found at 685.5 eV, which was higher than the 。 684.5 eV for NaF, signifying that surface reactions had occurred.
