Abstract
A bare graphite–polyurethane composite was evaluated as an alternative electrode in the determination of atenolol (ATN) in pharmaceutical formulations. Using a DPV procedure, a linear analytical curve was observed in the 4–100 μmol L−1 range with a LOD = 3.16 μmol L−1, without need of surface renewing between successive runs, with recoveries between 95.5 and 108%. Interference of other antihypertensive drugs was observed, but not from the usual components of tablets. The results of the proposed method agreed with HPLC ones within 95% confidence level.
