Preconcentration of lead using solidification of floating organic drop and its determination by electrothermal atomic absorption spectrometry
A simple microextraction method based on solidification of a floating organic drop (SFOD) was developed for preconcentration of lead prior to its determination by electrothermal atomic absorption spectrometry (ETAAS). Ammonium pyrolidinedithiocarbamate (APDC) was used as complexing agent, and the formed complex was extracted into a 20 μL of 1-undecanol. The extracted complex was diluted with et...
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 کاملDispersive Liquid-Liquid Microextraction Based on Solidification of Floating Organic Drop Combined with Flame Atomic Absorption Spectrometry for Preconcentration and Determination of Thallium(III) in Water Samples
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 کاملDispersive Liquid-liquid Microextraction Based on Solidification of Floating Organic Drop for Simultaneous Separation/preconcentration of Nickel, Cobalt and Copper Prior to Determination by Electrothermal Atomic Absorption Spectrometry
A dispersive liquid–liquid microextraction based on solidification of floating organic drop for simultaneous extraction of trace amounts of nickel, cobalt and copper followed by their determination with electrothermal atomic absorption spectrometry was developed. 300 μL of acetone and 1-undecanol was injected into an aqueous sample containing diethyldithiocarbamate complexes of metal ions. For ...
