Abstract
The present study deals with the application of ozone with perfluorooctylalumina in humic acids decomposition. Ozonation with perfluorooctylalumina addition destroys the complex structures in humic acids into relatively simple ones and color removal based on ADMI (American Dye Manufacture Index) measurement was greater than 95% in all tests. The rate of humic acids decomposition was described by using a first-order rate expression with respect to the decrease of A254. A central pH level (pH 7) and perfluorooctylalumina addition is helpful in humic acids decomposition. The modified-Nernst equation could be used to predict humic acids decomposition at varying reaction conditions.
