Flow-injection chemiluminescence determination of isoniazid using on-line electrogenerated BrO2 as an oxidant
By designing a novel electrolytic flow cell, the strong oxidant BrO2 was electrogenerated on-line in KBr solution and its concentration could be readily adjusted on-line with the flow-injection technique and an electrochemical method. The chemical reaction between BrO2 and luminol in alkaline medium is accompanied by weak emission of light due to chemiluminescence (CL). It was found that the is...
متن کاملFlow-injection Chemiluminescence Determination of Hydrazine Using On-line Electrogenerated B.rO- as the Oxidant
A novel chemilulninescence flow system for the determination ofhydrazine is presented. It is based on the enhancement effectofhydrazine on the chemiluminescence reaction between IUlninol and BrOin alkaline media. The oxidant BrOwas on-line electrogenerated by constant current electrolysis, resulting in the elimination ofthe inconvenience of its instability. The variables that affect the reactio...
متن کاملFlow injection chemiluminescence analysis for highly sensitive determination of noscapine
Noscapine is an antitussive drug and possesses potent antitumor activity. This work establishes a highly sensitive method for its determination by flow injection chemiluminescence (CL) technique. This method is based on its strong sensitizing effect on the weak CL reaction between sulfite and acidic permanganate. The mechanism for the sensitizing process is proposed on the basis of fluorescence...
متن کاملFlow-injection electrogenerated chemiluminescence determination of isoniazid using luminol.
Based on a new electrogenerated chemiluminescence (ECL) analytical idea, this paper explains a sensitive and selective flow-injection ECL method using luminol for the determination of isoniazid, based on the sensitizing effect of isoniazid for the weak ECL emission of electrochemically oxidized luminol. Under the optimum experimental conditions, the relative ECL intensity was linear with isonia...
متن کاملPermanganate-based chemiluminescence analysis of ferulic acid using flow injection.
A simple, sensitive and rapid flow-injection chemiluminescence method has been developed for the determination of ferulic acid based on the chemiluminescence reaction of ferulic acid with potassium permanganate in a nitric acid medium. A strong chemiluminescence signal was observed when ferulic acid was injected into an acidic potassium permanganate solution in a flow-cell. The present method a...
