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: H₂PO^4->;Cl^- >;Cu²⁺>;HCO^3-~CO₃^2-.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.
