A rapid vortex assisted-cloud point extraction (VA-CPE) method was developed to separate cadmium (Cd), copper (Cu), zinc (Zn) and lead (Pb) in accordance with important parameters. Cd Pb determined personnel care products (PCPs) by Electrothermal Atomic Absorption Spectrometry (ETAAS), however Cu Zn Flame (FAAS). Triton X-100 xylenol orange were used as a chelating agent. The factors including ...

The study monitored the effect of differentiated mineral nutrition microgreens species by solution sodium selenate (2 mg Se/L) on content Se, chlorophylls, and other minerals. Chlorophylls were measured spectrophotometrically, Se electrothermal atomic absorption method (ETAAS) with Zeeman-effect background elements’ concentration was performed a dual Inductively coupled plasma emission spectros...

A method is described for direct electrothermal atomic absorption spectrometric (ETAAS) determination of cadmium in untreated samples of wine. Pyrolytic graphite tubes and graphite tubes with standard L'vov pyrolytic platforms were tested as atomizers. The detection limit achieved was 0.08 microg L(-1) Cd in wine. The relative standard deviation for the concentration range from 0.2 to 10 microg...

Electrothermal atomic absorption spectrometry (ETAAS) is considered the most common and advanced technique to determine trace lithium in biological fluids. However, chloride existing in samples has been reported to create serious interferences. Nitric acid was verified as a chemical modifier to eliminate the interference of chloride in determining trace lithium in urine samples and the possible...

A large-volume (100 microl) injection-ETAAS with W-treated PG furnace combined with a phosphate modifier was applied to the determination of unpolluted levels of Cd in tap, snow and river-water samples. The limit of detection of 1.1 ng l(-1) was observed for a 4 w/v% NH4H2PO4 modifer. Matrix interference studies were tested for major ion species well found in fresh water. The direct determinati...

A procedure for the determination of the total content of arsenic in urine, serum and blood by electrothermal atomic absorption spectrometry (ETAAS) is described. Zeeman correction is used to compensate the high background signals. The samples are diluted (1 + 1 for urine and 1 + 3 for both serum and blood samples) in a medium containing 0.1% w/v Triton X-100 before being introduced directly in...
