Effect of Inorganic Ions on Fenton's Reagent Catalytic Degradation of Phenol in Water

The effect of inorganic ions on Fenton's reagent to degrade phenol in water is studied. Experimental results show that ferric ions can enhance the catalyst-oxidation ability of Fenton's reagent. Phosphate,chloride ions, copper ions and carbonate ions will suppress the catalyst-oxidation ability, and the inhibition ability of ions is: H

.For the ions of sulfate radical, nitrate radical and ammonium, the effect of these ions on the Fenton's reagent was not found. On the other hand, the action mechanics of inhibition of the inorganic are discussed.
