Nanogold-Decorated Silica Monoliths as Highly Efficient Solid-Phase Adsorbent for Ultratrace Mercury Analysis in Natural Waters

26-Oct-2015 | Jessica Huber; Lars-Eric Heimbürger; Jeroen E. Sonke; Sebastian Ziller; Mika Lindén; Kerstin Leopold, Analytical Chemistry, 2015

We propose a novel analytical method for mercury (Hg) trace determination based on direct Hg preconcentration from aqueous solution onto a gold nanoparticle-decorated silica monolith (AuNP@SiO2). Detection of Hg is performed after thermal desorption by means of atomic fluorescence spectrometry. ...

Nanomaterials-based approaches for the detection and speciation of mercury

21-Oct-2015 | xiaohan Xu; Yu-Feng Li; Jiating Zhao; Yunyun Li; Jing Lin; Bai Li; Yuxi Gao; Chunying Chen, Analyst, 2015

Mercury is toxic with widespread contamination. High sensitive and selective approaches for mercury analysis are desired. Although convention analytical techniques are accurate and sensitive in the determination of mercury, these procedures are time-consuming, labor-intensive and dependent ...

Recent Advances in the Analysis of Mercury in Water - Review

20-Oct-2015 | Kallithrakas-Kontos, Nikolaos; Foteinis, Spyros, Current Analytical Chemistry, 2015

Abstract: Mercury is one of the most toxic elements that may be found in natural water bodies and can negatively affect living organisms, human health as well as drinking water quality. In addition, water is the main transportation and transformation pathway of mercury into the environment ...

IJERPH, Vol. 12, Pages 8811-8827: Accumulation of Heavy Metals and Metalloid in Foodstuffs from Agricultural Soils around Tarkwa Area in Ghana, and Associated Human Health Risks

28-Jul-2015 | Bortey-Sam, Nesta ; Nakayama, Shouta M. M.; Akoto, Osei ; Ikenaka, Yoshinori ; Fobil, Julius N.; Baidoo, Elvis ; Miz ..., International Journal of Environmental Research and Public Health, 2015

This study was carried out to assess the extent of heavy metals and metalloid accumulation from agricultural soils to foodstuffs (viz, M. esculenta (cassava) and Musa paradisiaca (plantain)) around thirteen neighboring communities within Tarkwa, Ghana; and to estimate the human health risk ...

Direct mercury analysis in environmental solids by ICP-MS with on-line sample ashing and mercury pre-concentration using a direct mercury analyzer

07-May-2015 | Derek D. Bussan; Ryan F. Sessums; James V. Cizdziel, Journal of Analytical Atomic Spectrometry, 2015

A commercially available direct mercury analyzer (DMA) based on sample combustion, pre-concentration by amalgamation with gold, and atomic absorption spectrophotometry (AAS) was coupled to a sector field inductively coupled plasma mass spectrometer (ICP-MS). The combined system (DMA-ICP-MS) was ...

Coupling Laser Ablation and Atomic Fluorescence Spectrophotometry: An Example Using Mercury Analysis of Small Sections of Fish Scales

29-Oct-2010 | Luc Beaudin; Sophia C. Johannessen; Robie W. Macdonald, Analytical Chemistry, 2010

Mercury is a toxic element that exchanges among air, water, and sediments and biomagnifies into high trophic level organisms. Here, we present a novel combination of laser ablation with relatively low-cost cold vapor atomic fluorescence spectrophotometry to analyze Hg vaporized from targeted ...

Comparison of neutron activation analysis with conventional detection techniques for the evaluation of trace elemental contamination in Mallard (Anas platyrhynchos) feathers

19-Aug-2010 | Stacey D. Haskins, David G. Kelly, Ron D. Weir, Journal of Radioanalytical and Nuclear Chemistry, 2010

Instrumental neutron activation analysis (INAA) was used to determine trace elemental contamination in bird feathers. Primary feathers from twelve mallard (Anas platyrhynchos) ducks, migrating through the Thousand Islands region of Ontario, Canada, were analyzed for selenium, mercury, chromium, ...
