A SEQUENTIAL ZERO VALENT IRON AND AEROBIC BIODEGRADATION TREATMENT SYSTEM FOR NITROBENZENE

BELL L. S. / DEVLIN J. F. / GILLHAM R. W. / et al. - ARTICLE DE PERIODIQUE - 2003

Nitroaromatic compounds are resistant to biodegradation and, when they do transform, the degradation of the products may also be incomplete. Nitrobenzene was chosen to assess the feasibility of an in situ multi-zone treatment system at the laboratory scale. The treatment system consists of a zero valent granular iron zone to reduce nitrobenzene to aniline, followed by a passive oxygen release zone for the aerobic biodegradation of the aniline daughter product.
