Potentiometric determination of phosphorus in biodiesel using chemically modified electrode with cobalt film

Potentiometric determination of phosphorus in biodiesel using chemically modified electrode with cobalt film

A cobalt film modified glassy carbon electrode was prepared by electrochemical deposition and its application was studied by potentiometry. The film modified electrode is used for the determination of phosphorus and exhibits a detection limit of 8.7×10−5molL−1 with recovery of 96.9%. This method has...

Zusammenfassung:A cobalt film modified glassy carbon electrode was prepared by electrochemical deposition and its application was studied by potentiometry. The film modified electrode is used for the determination of phosphorus and exhibits a detection limit of 8.7×10−5molL−1 with recovery of 96.9%. This method has been used for determination of phosphorus ions in biodiesel samples with satisfactory results.
