Fluorescence determination of the pesticide asulam by flow injection analysis.
This paper presents the analytical determination of the pesticide Asulam based on its native fluorescence. The method was optimized in either a flow injection analysis (FIA) assembly or in batch. The maximum fluorescence intensity was observed for basic pH solutions and at a lamda(ex) of 258 nm and a lamda(em) of 342 nm. The influence of different empirical parameters, such as the pH, the prese...
متن کاملUltra-trace Determination of Palladium(II) by Spectrophotometric Flow Injection Analysis
Nowadays, palladium compounds due to their especial characteristics used in different industries, mainly in electrical power sources and chemical productions as a catalyst. Therefore, Pd concentration is increasing in our around that can be contaminant our environment due its toxic effects. In this work, a simple, selective and rapid flow injection method of analysis (FIA) has been developed fo...
متن کاملChemiluminescent determination of the pesticide bromoxynil by on-line photodegradation in a flow-injection system.
A new, robust and simple method is proposed for the chemiluminescent determination of the pesticide Bromoxynil. The empirical procedure is performed with the aid of a flow-injection manifold provided with an on-line photo-reactor to obtain chemiluminescent photofragments. After a period of 12 s of irradiation with an 8 W low-pressure mercury lamp, a chemiluminescent oxidation was performed with...
متن کاملSpectrophotometric determination of catecholamines with metaperiodate by flow-injection analysis
A flow-injection spectrophotometric method for the determination of adrenaline and isoprenaline, based on the reaction with metaperiodate, is described. The calibration graphs are linear up to 2X 10e4 M. Flow injection allows the measurement of 120 samples per hour. The method was successfully applied to the determination of both catecholamines in pharmaceuticals.
متن کاملSequential determination of iron and titanium by flow-injection analysis.
A flow-injection method has been developed for the sequential spectrophotometric determination of iron and titanium using 3,4 dihydroxybenzoic acid as chromogenic reagent. The system involves the sequential measurement of the absorbances of the complexes at 380 and 570 nm. The system is designed using a simultaneous injection of sample and reagent into separate carrier streams. The proposed met...
