A novel solidified floating organic drop microextraction method for preconcentration and determination of copper ions by flow injection flame atomic absorption spectrometry.
A rapid, simple and cost effective solidified floating organic drop microextraction (SFODME) and flow injection flame atomic absorption spectrometric determination (FI-FAAS) method for copper was developed. In this method, a free microdrop of 1-undecanol containing 1,5-diphenyl carbazide (DPC) as the complexing agent was transferred to the surface of an aqueous sample including Cu(II) ions, whi...

Dispersive Liquid-Liquid MicroExtraction technique based on Solidification of a Floating Organic drop (DLLME-SFO) combined with flame atomic absorption spectrometry was developed for determination of thallium in water sample. An appropriate mixture of acetone and 1-undecanol was rapidly injected into an aqueous sample containing TlCl4- which forms an ion pair with bril...
متن کاملDetermination of Cadmium by Electrothermal Atomic Absorption Spectrometry after its Separation and Preconcentration by Syringe to Syringe Dispersive Liquid Phase Microextraction-Solidified Floating Organic Drop
The application of syringe to syringe dispersive liquid phase microextraction-solidified floating organic drop was extended for the separation and preconcentration of trace amounts of cadmium ions from water and cereal samples. The extracted cadmium was quantified by electrothermal atomic absorption spectrometry. Factors affecting the complex formation as well as microextraction efficiency such...
متن کاملPreconcentration and determination of palladium water samples by ionic liquid - dispersive liquid liquid microextraction combined with flame atomic absorption spectrometry
A simple, rapid and efficient dispersive liquid–liquid microextraction by use of ionic liquid (IL-DLLME)method, followed by flame atomic absorption spectrometry (FAAS) was developed for the preconcentrationand determination of palladium in water samples. In this method, an appropriate mixture of acetone and octylmethyl imidazolium hexafluorophosphate was injected rapidly into the aqueous sample...
متن کاملDispersive liquid–liquid microextraction based on solidification of floating organic drop combined with flame atomic absorption spectrometry for determination trace amount of cobalt in water samples
An efficient, rapid, simple, and highly selective dispersive liquid–liquid microextraction basedon solidification of floating organic drop (DLLME-SFOD), combined with flame atomicabsorption spectrometry was developed for preconcentration and determination of trace amountsof cobalt in water samples. In this method, an appropriate mixture of acetone and1-undecanol was injected rapidly into the aq...
