The present work describes a sensor is composed of incorporated Rofenac D as an electro active material in PVC matrix membrane and dioctylphthalate or dioctylesepacate as solvent mediators. The sensor exhibited fast and stable near Nernstian cationic response of 29.1 ±0.5 mV Concentration decade of iron (II) in the concentration range of 1.0× 10-7 -1.0× 10-2 M. The lower limit of detection was 1.5× 10-7± 0.2. It is to be noted that the sensor based on Rofinac D was used throughout this investigation in the pH range 3- 8.5. The sensor displayed a good selectivity for iron ion respect to a number of common foreign inorganic and organic species spatially some drugs which contains iron. The results obtained with this procedure were compared with those from atomic absorption and spectrophotometry.
