Determination of twelve elements including major and trace elements in coal with flame atomic absorption spectrometry

Determination of Trace Elements in Rice Products by Flame and Graphite Furnace Atomic Absorption Spectrometry

The Thermo Scientific iCE 3000 Series Atomic Absorption Spectrometers are the ideal tool for the accurate and rapid determination of multiple trace elements in rice products. Flame atomic absorption can be used as a fast screening tool for the analysis of nutritional elements such as copper, manganese and zinc, while graphite furnace atomic absorption can be used for the accurate determination ...

The Analysis of Trace Elements in Honey by Flame and Graphite Furnace Atomic Absorption Spectrometry

Determination 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...

Development of ultrasound-assisted emulsification microextraction for the determination of trace zinc and copper by flame atomic absorption spectrometry

In this work, we developed a method based on ultrasound-assisted emulsification microextraction (USAEME) for the determination of zinc and copper by flame atomic absorption spectrometry (FAAS). The method is based on the use of the organic solvent carbon tetrachloride (CCl4) as an extraction solvent. In order to obtain a high enrichment factor, the effect of different parameters affecting the c...

Determination of Trace Elements in Iron Minerals by Atomic Absorption Spectrometry

A method for the determination of lead, cobalt, nickel, chromium, zinc and manganese in iron minerals siderite (FeCO3), hematite (Fe2O3), pyrite and marcasite (FeS2)by flame and Zeeman electrothermal atomic absorption spectrometry (ETAAS) was developed. Interferences were investigated by measuring the absorbance of the elements investigated in series of samples with varying mass ratios of the e...
