Quinoline-8-ol and its derivatives as preconcentration agents in flow injection analysis coupled to atomic and molecular spectrometric techniques.
Quinoline-8-ol, one of the most popular and versatile organic reagents, is known to react with several metals, because it has both a basic nitrogen and a phenolic group. Hence, quinoline-8-ol and its derivatives have been widely used as chelating and/or sorbent extraction agents in on-line flow injection analysis (FIA) along with a suitable detection technique. The state of the art for using qu...
متن کاملContinuous ultrasound-assisted extraction of iron from mussel samples coupled to a flow injection-atomic spectrometric system
Iron was extracted on-line from solid mussel samples by a simple continuous ultrasound-assisted extraction system (CUES) connected to a flow injection manifold, followed by on-line flame atomic absorption spectrometric determination. An experimental design was used for the optimisation of the CUES. The method allowed a total sampling frequency of 11 samples per hour, with a relative standard de...
متن کاملFlow injection/atomic absorption spectrometric determination of zineb in commercial formulations of pesticide based on slurry sampling.
This paper reports on a new strategy for the slurry sampling determination of dithiocarbamate pesticide zineb [[ethylenebis(dithiocarbamato)]zinc] employing a FIA system with a flame atomic absorption spectrometry detector. In the flow system, an on-line alkaline hydrolysis of the pesticide is performed, allowing the release of Zn(II) ions to the solution, which are easily detected by a flame A...

متن کاملA versatile injection system for flow-injection analysis
Analyser injection systems based on the principle of flow-injection analysis depend on the technique used. They generally take the form of an injection loop valve; the injected sample volume is determined by the volume of the valve. Injection systems are seldom designed with a time factor to define this volume. The authors report on an original injection system, which enables the two techniques...
