Determination of Lanthanoids in Seawater by Inductively Coupled Plasma Mass Spectrometry after Pre-Concentration with a Chelating Resin Disk
A seawater sample was analyzed for its lanthanoids (Ln’s) contents by inductively coupled plasma mass spectrometry (ICP-MS). The analytical procedure included the pre-concentration and partial purification of Ln’s with a chelating resin disk and the employment of the combination of the internal standard and standard addition methods in ICP-MS, which seemed indispensable for the determination of...
متن کاملFast Determination of Yttrium and Rare Earth Elements in Seawater by Inductively Coupled Plasma-Mass Spectrometry after Online Flow Injection Pretreatment.
A method for daily monitoring of yttrium and rare earth elements (YREEs) in seawater using a cheap flow injection system online coupled to inductively coupled plasma-mass spectrometry is reported. Toyopearl AF Chelate 650M® resin permits separation and concentration of YREEs using a simple external calibration. A running cycle consumed 6 mL sample and took 5.3 min, providing a throughput of 11 ...
متن کاملIodine determination in food by inductively coupled plasma mass spectrometry after digestion by microwave-induced combustion.
Iodine determination in food samples was performed by inductively coupled plasma mass spectrometry (ICP-MS) after digestion by microwave-induced combustion (MIC). Sample masses up to 500 mg of bovine liver, corn starch, milk powder, or wheat flour were completely combusted using the MIC system. Ammonium nitrate (6 mol l(-1) solution, 50 μl) was used as an aid for ignition and vessels were charg...
متن کاملDetermination of Lead and Strontium Isotope Ratios in Wines by Inductively Coupled Plasma Mass Spectrometry
Thirteen wine assortments from Romania were investigated from the point of view of their metal content and isotopic ratios Pb/Pb and Sr/Sr. The determination was performed by ICP-QMS. The aim of this study was to detect and quantitatively determine the toxic metals in some white and red wine samples and to investigate them from the point of view of isotopic ratios Pb/Pb and Sr/Sr. Six metals wi...
