Abstract

A novel modified carbon nanotube paste electrode of 2-(4-oxo-3-phenyl-3,4-dihydro-quinazolinyl)-N'-phenyl-hydrazinecarbothioamide (2PHC) was fabricated, and the electro-oxidation of epinephrine (EP), norepinephrine (NE), and their mixture has been studied using electrochemical methods. The modified ...
