Kinetics of aerobic biodegradation are studied for 20 aromatic species by using sludges taken from a municipal sewage treatment plant. The reproducibility of the results is tested with respect to the period of collection of the sludges and the wastewater treatment plant were they are taken. The comparison of kinetic constants estimated for investigated chemicals allows to evaluate the effect on the reactivity due to the presence of single groups (i.e., -OH, -CH3, -Cl, -NO2) into the aromatic structures. The search for easy structure-reactivity relationships is also attempted by using some group contributing methods.

Abstract
Kinetics of aerobic biodegradation are studied for 20 aromatic species by using sludges taken from a municipal sewage treatment plant. The reproducibility of the results is tested with respect to the period of collection of the sludges and the wastewater treatment plant were they are taken. The comparison of kinetic constants estimated for investigated chemicals allows to evaluate the effect on the reactivity due to the presence of single groups (i.e., -OH, -CH3, -Cl, -NO2) into the aromatic structures. The search for easy structure-reactivity relationships is also attempted by using some group contributing methods.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
