Abstract:

Zerovalent iron was used to degrade 16 polycyclic aromatic hydrocarbons (PAHs) in sediments. Effects of temperature, particle size of zerovalent iron, zerovalent iron dosage were studied by the orthogonal experiment. The laboratory experimental results show that the average removal efficiency could reach 56.95% at a temperature of 25 ℃, a particle size of zerovalent iron 0.15 mm, and a zerovalent iron dosage of 2 g.

Key words: zerovalent iron, polycyclic aromatic hydrocarbons (PAHs), orthogonal experiment, effect factors
