Zero Valent Iron Particles for the Degradation of Polycyclic Aromatic Hydrocarbons in Contaminated Soil


Article Preview

The removal of polycyclic aromatic hydrocarbons (PAHs) from contaminated soil through oxidative degradation by zero valent iron (ZVI) has been investigated in this study. The results showed a fast decrease of PAHs within the first 30 minutes of treatment followed by a slow degradation. The degradation rates coefficient (k) of PAHs analysed using pseudo first-order rate model showed the rate of reaction increased with the increase of ZVI concentrations from 0.003 min-1 at 1% ZVI concentration to 0.011 min-1 at 3% ZVI. However, the normalized surface area constant (kSA) decreased when the ZVI dosage above 3% was applied.
