Determination of cadmium in wine by electrothermal atomic absorption spectrometry.

Determination 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...

Determination of lead and cadmium in water samples by cloud point extraction prior to flame atomic absorption spectrometry determination

Pb and Cd in water samples were determined by cloud point extraction (CPE) with sodiumdiethyldithiocarbamate (DDTC) as the chelating agent and octylphenoxypolyethanl (Triton X-114) asthe surfactant prior to flame atomic absorption spectrometry (FAAS) determination. The main factorsof affecting the extraction and detection processes were optimized. The preconcentration of 10 mL ofstandard soluti...

Determination of Cd anD Pb in fuel ethanol by filter furnaCe eleCtrothermal atomiC absorPtion sPeCtrometry

DETERMINATION OF Cd AND Pb IN FUEL ETHANOL BY FILTER FURNACE ELECTROTHERMAL ATOMIC ABSORPTION SPECTROMETRY. A method was developed for quantification of Cd and Pb in ethanol fuel by filter furnace atomic absorption spectrometry. Filter furnace was used to eliminate the need for chemical modification, to stabilize volatile analytes and to allow the application of short pyrolysis step. The determ...

Flotation/magnetic stirring-assisted liquid-liquid microextraction combined with flame atomic absorption spectrometry for the preconcentration and determination of cadmium (II) after optimization using experimental design

Arapid, highly sensitive and efficient flotation/magnetic stirring-assisted liquid-liquid microextraction combined with flame atomic absorption spectrometry has been proposed for the preconcentration and quantitative analysis of trace amounts of cadmium (II) in the presence of sodium diethyldithiocarbamateas complexingagent. Parameters including sample pH, concentration of the complexingagent, ...
