Flow-injection chemiluminescence determination of manganese(II) in natural water with solid sodium bismuthate as an oxidant.

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...

Photodegradation and flow-injection determination of dithiocarbamate fungicides in natural water with chemiluminescence detection.

A simple and rapid flow-injection method is reported for the determination of dithiocarbamate fungicides (maneb, nabam and thiram) based on chemiluminescence detection. The method involves the photodegradation of dithiocarbamate fungicides via UV light in an alkaline medium. Photoproducts are then reacted with luminol in the absence of an oxidant. Linear calibration graphs were obtained in the ...

Flow injection photoinduced chemiluminescence determination of imazalil in water samples.

In this work, a fast, simple and economic method is proposed for the determination of imazalil in water samples by flow injection photoinduced chemiluminescence. In this method, imazalil degrades in basic media through the use of a photoreactor, and the resulting photofragments react with ferricyanide and generate the direct chemiluminescence signal. To the authors' knowledge, this is the first...

Flow-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...
