Flow-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 کاملFlow-injection chemiluminescence and electrogenerated chemiluminescence determination of escitalopram oxalate in tablet form.
Rapid, simple and highly sensitive flow-injection (FI) chemiluminescence (CL) and flow-injection electrogenerated chemiluminescence (ECL) methods were developed for the determination of escitalopram oxalate (ESC), a selective serotonin reuptake inhibitor used as an antidepressant drug. The CL method was based on the CL reaction of ESC with acidic cerium(IV) and tris(2,2'-bipyridyl)ruthenium(II)...
متن کاملElectrogenerated chemiluminescence. 58. Ligand-sensitized electrogenerated chemiluminescence in europium labels.
The electrochemistry and electrogenerated chemiluminescence (ECL) of a series of europium chelates, cryptates, and mixed-ligand chelate/cryptand complexes were studied. The complexes were of the following general forms: EuL(4)(-), where L = β-diketonate, a bis-chelating ligand (such as dibenzoylmethide), added as salts (A)EuL(4), where A = tetrabutylammonium ion or piperidinium ion (pipH(+)); ...
متن کاملFlow-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...
