Abstract
The effectiveness of biosparging to mitigate NN diethylaniline in aquifer was evaluated by measuring the time course of decrease in concentration of the aforementioned compound in aerobic microcosm experiments The firstorder kinetic constant for NN diethylaniline aerobic biodegradation was estimated from microcosm data 0037 ± 0004 d−1 and the value was consistent with the bestfitting value in the transport and reaction model of the aquifer 0020 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 NN diethyl aniline under the aforementioned aquifer conditionAuthors gratefully acknowledge Barbara Bosio and Eleonora Gaspari for their precious help in microbiological analyses and RC Lab Srl Italy for technical assistance in chemical analyses This work was partially funded by Consorzio Copernico Scarl Italy
