Biodegradation | Year: 2010

The effectiveness of biosparging to mitigate N,N diethylaniline in aquifer was evaluated by measuring the time course of decrease in concentration of the aforementioned compound in aerobic microcosm experiments. The first-order kinetic constant for N,N diethylaniline aerobic biodegradation was estimated from microcosm data (0. 037 ± 0. 004 d-1), and the value was consistent with the best-fitting value in the transport and reaction model of the aquifer (0. 020 d-1). Furthermore, the biodegradability of the compound was evaluated under anaerobic condition in microcosm experiments, which was supported by field modelling. There was no significant degradation in the anaerobic microcosm experiments, confirming the recalcitrance of N,N diethyl aniline under the aforementioned aquifer condition. © Springer Science+Business Media B.V. 2009.
