Abstract
Monosubstituted phenols (meta or para substituents: MeO, C1, CN, NO2) were used as inhibitors of the phenol degradation by an activated sludge. By kinetic measurements, the inhibiting action was expressed as pI50, and the latter quantity was correlated with structural properties (logP, σ) of the inhibitors. The QSAR referring to the present system is compared with previous correlations based on different sludges and different sets of inhibitors, showing that the largely predominant factor of phenolic inhibition can be the phenol's lipophilicity.
