摘要
基于一种新型流通电解池的设计,结合恒电流电解技术与流动注射技术,使电生于电极表面附近的溴具有初生态的化学发光反应活性.它可直接氧化异烟肼而产生强度高、反应速度快的化学发光现象,据此建立了测定异烟肼的电化学发光新方法,同时,提出了一种研究、探索初生态试剂化学发光分析的新思想和新方法.
By both designing a novel electrolytic flow cell and using the flow - injection technique, the nascent Br-2 was in situ. electrogenerated on the surface of platinum electrode with constant current electrolytic method in the H2SO4 - KBr medium. It was then found that compared with reagent Br-2 as well as on - line electrogenerated Br-2, the in situ electrogenerated Br-2 could oxidize the isoniazid injected accompanying by a stronger chemiluminescence signal. Based on this observation, a new now - injection electrogenerated chemiluminescence method for the determination of isoniazid was proposed. At the same time, a new concept, which can be used to explore the CL properties of the in situ electrogenerated reagent and to improve the sensitivity of CL analysis, was also proposed.
