Abstract

The effects of pH and concentration of working buffer on the potentiometric response of a penicillin sensor based on a carboxyl-substituted poly (vinyl chloride)-coated Ag electrode were examined. The sensor showed a good response in buffer solutions of pH 6.5—8.5. The buffer concentration affected the response of the sensor. Higher concentration buffer (30 mM) strongly disturbed the response due to the higher buffer capacity.
