摘要

Fluoxetine is one of the most prescribed antidepressant drug. Two kinds of potentiometric sensor weremade for determination of fluoxetine. Both sensors respond based on ion-exchange mechanism. Inconstruction of two electrodes fluoxetine-tetraphenylborate ion-pair was used as a sensing element.PVC membrane electrode was made after series of experiments. The best PVC membrane electrodewas made of a composition of 28% PVC, 64% DBP, 2% NaTPB and 6% ion-pair. Nano-compositecarbon paste electrode was then constructed to have better analytical responses. The carbon pasteelectrode incorporation of multi-walled carbon nano-tube (MWCNTs) and nano-silica showed a betterresponse especially in term of lifetime and response time. The best nano-composite electrode wascomposed of 25% ion-pair, 4% MWCNTs, 1% nano-silica, 30% paraffin and 40% graphite. Theproposed method was successfully applied in determination of fluoxetine in its formulation.
