Determination of heavy metals and rare earth elements in environmental samples by ICP-MS after solid phase preconcentration with chelating resin fibers and anion exchanger filters.
A solid phase collection/concentration method using anion exchanger filters and a small syringe packed with chelating resin fibers is adopted as a preconcentration tool for trace elements and a separation tool for matrices in aqueous samples prior to the measurement by inductively coupled plasma-mass spectrometry (ICP-MS). The effects of fiber volume, sample volume, eluent volume, and sample fl...
متن کاملDetermination of Trace Elements in Edible Nuts in the Beijing Market by ICP-M.
Nuts have received increased attention from the public in recent years as important sources of some essential elements, and information on the levels of elements in edible nuts is useful to consumers. Determination of the elemental distributions in nuts is not only necessary in evaluating the total dietary intake of the essential elements, but also useful in detecting heavy metal contamination ...

متن کاملInfluence of digestion procedures on the determination of rare earth elements in peat and plant samples by USN-ICP-MS
Analytical procedures for the determination of rare earth elements (REE) in 250 mg aliquots of difficult-todigest peat and plant matrices by ICP-MS were developed. Three different pressurised digestion approaches were tested for this purpose, namely (i) closed vessel acid digestion on a hot-plate at 180 uC, (ii) digestion in a microwave high pressure autoclave at a temperature of 240 uC and (ii...
متن کاملDetermination of trace elements in filtered suspended marine particulate material by sector field HR-ICP-MS
Quantification of particulate (w0.45 mm) and dissolved (v0.45 mm) trace elements in seawater is imperative for understanding geochemical cycling in the marine environment. Suspended particulate trace element concentrations are typically v10% of total element concentrations in seawater. To overcome analytical difficulties associated with low analyte concentrations, it is common to filter large v...
