Potentiometric Sensors for Determination of Cefepime in Water and Biological Environments

Potentiometric cefepime sensors based on an organic ion-exchanger such as cefepime with tetraphenylborate are developed. The optimum membrane composition is established. The surface and volume properties of membranes are investigated. The constant of dissociation of the ion-exchanger in a membrane phase is calculated by stationary resistance. Potentiometric determination of cefepime in water and biological environments is present.
