Simplified Chemiluminescent Fia for Oxidimetric Determination of Captan
نویسندگان
چکیده
A new cherniluminescent reaction for captan-hydrogen peroxide in alkaline medium is described and applied through a FIA manifold to a determination of captan. The FIA assembly consists of a channel in which the oxidant (hydrogen peroxide) and the medium (NaOH solution) are mixed in situ and then the resulting mixture merges with the carrier (NaOH solution) where an aliquot of 582.1 p1 of the sample solution was inserted. The calibration graph was studied over the range 0.9-400 mg I", with a rsd and limit of detection of 1.8% (30 replicates) and 0.9 mg 1", respectively. The sample frequency was 160 h"'.

Sorption of platinum on immobilized microorganisms for its on-line preconcentration and chemiluminescent determination in water samples
Fungi of the type Aspergillus sp. were immobilized on a cellulosic resin and used as a biosorbent for the on-line preconcentration and separation of Pt(IV) ions prior to their chemiluminescent determination via flow injection analysis. Biosorption and elution conditions were optimized, and the results compared to biosorbents based on the use of Chlorella vulgaris algae and Saccharomyces cerevis...
متن کاملDetermination of albumin in biological fluids by flow injection analysis using the peroxyoxalate chemiluminescent system in micellar medium.
A new sensitive analytical procedure for the determination of albumin is presented, based on the participation of a fluorescent derivative of the protein in the peroxyoxalate chemiluminescent system using imidazole as a catalyst. The chemiluminescent emission is detected in a flow injection analysis (FIA) system, employing micellar medium as carrier, whereas the derivatisation reaction is carri...
متن کاملDetermination of iron-porphyrin-like complexes at nanomolar levels in seawater.
A new method for the non-specific determination of iron-porphyrin-like complexes in natural waters has been developed. It is based on the chemiluminescent oxidation of the luminol in the presence of dioxygen (O2) at pH 13. The method has been implemented in a FIA manifold that allowed the direct injection of seawater. The limit of detection is 0.11 nM of equivalent hemin (Fe-protoporphyrin IX)....
متن کاملPhotometric Determination of Boron with Azomethine-H Using Simplified Two-channel Flow Injection Analysis
A flow injection analysis (FIA) for boron determination was studied using a compact and simple two-channel manifold. This method is based on the chromogenic reaction of borate with azomethine-H to form a yellow complex. The absorbance of the complex was measured at 405 nm. The chemical factors and FIA variables influencing the color development were examined. When a 0.5% (w/v) azomethine-H solu...

The determination of dimethoate using either its native chemiluminescent (CL) properties or its photoinduced chemiluminescence obtained by irradiation with a 15 W low-pressure mercury lamp was studied. Thereby, two flow injection systems (FIA) with and without irradiation were exhaustively optimized and their analytical characteristics studied. Better sensitivity and selectivity was found in ab...
