Potentiometric Sensor for Benzylpenicillin Determination

A potentiometric benzylpenicillin-sensitive sensor with a plasticized polyvinyl-chloride membrane was developed. The sensor contains a benzylpenicillin—rhodamine 6G ion pair. The response is linear for benzylpenicillin concentrations in the range 10 –3 – 10 –1 M with an electrode-function slope char...

Description
Summary:A potentiometric benzylpenicillin-sensitive sensor with a plasticized polyvinyl-chloride membrane was developed. The sensor contains a benzylpenicillin—rhodamine 6G ion pair. The response is linear for benzylpenicillin concentrations in the range 10 –3 – 10 –1 M with an electrode-function slope characteristic of singly charged anions and a minimum detected concentration of (6.3 – 7.9) × 10 –4 M. This sensor could be used to detect and determine benzylpenicillin in pharmaceuticals.
