Formation of Polystyrene Coated Persulfate Slow-Release Candles for Polycyclic Aromatic Hydrocarbon Oxidation in Water

초록

Slow-release oxidation is important for effectively and selectively treating aromatic hydrocarbon pollutants like phenol in water. This research work focuses on persulfate candles formation for slow-relaese oxidation of phenol in water. To control the persulfate release rate polystyrene coating was applied to the beads. Four predetermined PAHs to ferrous molar ratios accompanied with persulfate candles were applied for the oxidation process. In the presence of ferrous activator the degradation of phenol was achieved. The increasing concentration of ferrous with constant persulfate and phenol concentration the higher degradation can be achieved up to certain Ph:Fe+2 ratio. The crossing the optimum ratio the inhibition starts.
