A novel coated silver ketamine(I) electrode for potentiometric determination …

a b s t r a c t: A new ketamine coated silver electrode (KCSE) based on ketamine hydrochloride with sodium tetraphenylborate (KT-TPB) as electroactive material has been described. The influence of membrane composition,type of solvent mediators, kind of electroactive materials and interfering ions on the sensor was investigated.The sensor displays Nernstian response of 55.8 ± 0.3 mV/decade ove…
