摘要:

The analytical performance of two modified electrodes (a tyrosinase biosensor and a glassy carbon electrode (GCE) covered with poly[Ni-(protoporphyrin IX)dimethyl ester]) in comparison with the bare electrode has been evaluated in a flow injection system using standard solutions of oleuropein and olive oil samples. The tyrosinase biosensor appeared to be an appropriate device for the selective determination of phenols, moreover it can be easily incorporated in an on-line system. This method was used to evaluate the stability of the samples.
