15/2/2021, · ,Under, conditions of pH = 3.0, 2.2 mM PDS, 4 g/L fly ash and 300 min reaction time, 54% of COD was eliminated. The presence of 21.8% Fe 2 O 3 in fly ash structure improved the catalytic activity of fly ash. Moreover, ,acidic, conditions can help induce iron leaching into the solution and initiate homogenous activation of PDS.
