Application of solvent-assisted dispersive solid phase extraction combined with flame atomic absorption spectroscopy for the determination of trace amounts of Cadmium
Introduction: Cadmium is recognized worldwide as a toxic metal. In this study, Solvent-Assisted Dispersive Solid Phase Extraction (SA-DSPE) combined with Flame Atomic Absorption Spectrometry (FAAS), was used for determination of trace amounts of Cadmium (Cd-II)) in drinking water samples. Correspondence: Omid Rahmanian, PhD. ...
متن کاملFeasibility evaluation of trace amount of zinc in urine samples using atomic absorption solidified floating organic drop micro-extraction technique
Background: The present study was carried out with the aim of extracting trace amounts of zinc in urine samples with ultrasound-assisted emulsification solidified floating organic drop micro-extraction (USAE-SFODME) method by flame atomic absorption spectrometry (FAAS). The efficiency was investigated using the solvent extraction volume, extraction pH, time sonication and temperature extraction...
متن کاملDetermination 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...
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...
متن کاملDetermination of Trace Copper(II) in Food Samples by Flame Atomic Absorption Spectrometry after Cloud Point Extraction
A new method for the determination of trace copper(II) in food samples by Cloud Point Extraction(CPE) combined with Flame Atomic Absorption Spectrometry(FAAS) is presented and evaluated. The method is based on the fact that hydrophobic complex of copper(II) with sodium diethyldithiocarbamate (DDTC) was formed at pH 6.0 and subsequently the hydrophobic complex was extracted into surfactant-r...
