A combination of trace elements preconcentration and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) is proposed for the analysis high purity substances.The analytical figures merit this were evaluated using germanium dioxide as an example.Trace preconcentrated by volatization in form tetrachloride from sample solutions.The concentrate was evaporated to dryness on surface a high-purity silicon substrate analyzed LA-ICP-MS.Indium used internal standard obtain...
The 650–621 Ma plume which impinged beneath the Siberian craton during breakup of Rodinia caused formation several alkaline carbonatite massifs in margins Angara rift system. Beloziminsky ultramafic massif (BZM) Urik-Iya graben includes alnöites, phlogopite carbonatites and aillikites. Yuzhnaya pipe (YuP) ~ 645 640–621 aillikites BZM, dated by 40Ar/39Ar, contain xenoliths carbonated sulfide-bearing dunites, xenocrysts olivines, Cr-diopsides, Cr-phlogopites, Cr-spinels (P 4–2 GPa T 800–1250...
The paper discusses using sorption preconcentration of elements from mineral waters by graphene oxide. procedure aims to extract heavy metals such as Cd, Cr, Cu, Pb, Zn and other analytes solution. Inductively coupled plasma – mass spectrometry (ICP-MS) inductively optical emission (ICP-OES) were used determine the analyte content. Graphene oxide was obtained microwave exfoliation graphite on at different pH values coexisting ion effect studied in detail. Preliminary provides good extraction...
Background: Heavy metals (HMs) such as Cr, Hg, Pb, etc., are major threats to human health due their toxic and carcinogenic properties. So, the determination of HMs concentrations in waters is an actual important task. Methods: In this paper, method includes a preliminary concentration other analytes (Ag, Au, Ba, Be, Bi, In, Sn, Zn) from water solutions on graphene oxide subsequent analysis slurries sorbent by electrothermal vaporization inductively coupled plasma optical emission...
Mineral data from Yakutian kimberlites allow reconstruction of the history lithospheric mantle. Differences occur in compositions mantle pyropes and clinopyroxenes large kimberlite pipes Alakit Daldyn fields. In field, Cr-diopsides are alkaline, Stykanskaya some other contain more sub-calcic dunitic-type diamond inclusions, while field harzburgitic frequent. The eclogitic inclusions sharply divided types conditions, they show varying often continuous Pressure–Temperature (P–T) ranges with...
Mantle xenoliths from Zarnitsa pipe studied in gray eruptive breccias (early) brown autholitic breccia (BAB) and black macrocrystic kimberlites (last dike; BMK), include garnet spinel dunites-harzburgites, pyroxenites, eclogites, glimmerites megacrysts. PT reconstructions using reveal sharply layered structure (8 levels), estimated with the single grain mineral estimates mark hot (Cpx, Ilm) cold (OPx, Gar) inflected geotherm. The interaction plume melts is found at lithosphere asthenosphere...
We have studied variations in the structure and composition of minerals from pipes Yakutian kimberlite province (YKP) different mantle terranes Siberian craton. The study was based on an extensive database, including microprobe analysis datasets consolidated by IGM, IG, IEC IGDNM SB RAS ALROSA geochemical performed LA‐ICP‐MS (Laser Ablation Inductively Coupled Plasma Mass Spectrometry). reconstruction shows layering under tubes, 6–7 slab that were probably formed due to subduction; slabs are...

The combination of two-jet arc plasma optical emission spectrometry (TJP-OES) and electrothermal vaporization (ETV) for sample introduction is proposed the first time.
Heavy metals are potent polluters of marine ecosystems. Consumption contaminated seafood may lead to adverse health effects. In this work, thick film modified graphite sensors used as working electrodes for the simultaneous determination copper, lead, cadmium and zinc in mussel tissue from Sea Japan. The samples were prepared by HNO3 wet mineralization analyzed pH 4 acetate buffer anodic stripping voltammetry. analytical signal was studied a function accumulation potential, time, sweep rate...
Major, minor and trace element compositions of mantle xenocrysts from Devonian kimberlite pipes in the Priazovie give an insight into structure beneath SE Ukranian Shield its evolution. Garnets yield low temperature conditions as determined by monomineral thermobarometry. The lithosphere is sharply divided at 4.2 GPa, marked a high Cpx-Ilm-Phl trend, eclogites changes pyrope geochemistry.
