Abstract
By both designing a novel electrolytic flow cell and using the flow - injec tion technique, the nascent Br-2 was in situ. electrogenerated on the surfa ce of platinum electrode with constant current electrolytic method in the H 2SO4 - KBr medium. It was then found that compared with reagent Br-2 as wel l as on - line electrogenerated Br-2, the in situ electrogenerated Br-2 cou ld oxidize the isoniazid injected accompanying by a stronger chemiluminesce nce signal. Based on this observation, a new now - injection electrogenerat ed chemiluminescence method for the determination of isoniazid was proposed . At the same time, a new concept, which can be used to explore the CL prop erties of the in situ electrogenerated reagent and to improve the sensitivi ty of CL analysis, was also proposed.
