Determination of iron in seawater by high-resolution isotope dilution inductively coupled plasma mass spectrometry after Mg(OH)2 coprecipitation

A simple, accurate and highly sensitive method has been developed for determining the concentration of Fe in seawater. The technique applies the low-blank Mg(OH)2 coprecipitation method of Wu and Boyle [Anal. Chem. 69 (1997) 2464±2470] to preconcentrate Fe from seawater, and uses isotope dilution high-resolution ICPMS detection to ensure accuracy and enable high sensitivity. This method has bee...

Sample pretreatment using chitosan-based chelating resin for the determination of trace metals in seawater samples by inductively coupled plasma-mass spectrometry.

A sample-pretreatment method using a chitosan-based chelating resin, ethylenediamine-N,N,N'-triacetate-type chitosan (EDTriA-type chitosan), was developed for the preconcentration of trace metals in seawater and separation of the seawater matrix prior to their determination by inductively coupled plasma-mass spectrometry (ICP-MS). The resin showed very good adsorption for transition metals and ...

Preconcentration and determination of trace metals in seawater using a thiol cotton fiber minicolumn coupled with inductively coupled plasma mass spectrometry.

A rapid separation and preconcentration method was developed for the determination of trace metals Cu, Zn, Cd, and Pb in seawater using a minicolumn packed with thiol cotton fiber (TCF) coupled with inductively coupled plasma mass spectrometry (ICP-MS). Preconcentration parameters, such as seawater sample volume and flow rate and eluent hydrochloric acid concentration, volume and flow rate, wer...

Determination of sulfur in fossil fuels by isotope dilution electrothermal vaporization inductively coupled plasma mass spectrometry

The determination of S by solution nebulization quadrupole inductively coupled plasma mass spectrometry (ICP-MS) is dif®cult because of interferences from oxygen dimer ions. The large O2 z ion current from the solvent water is a serious interference at S, the most abundant of the four isotopes, and precludes its measurement. The isotopic composition of S varies in nature as a consequence of nat...

Determination 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...
