Atomic spectrometry updates. Review of advances in elemental speciation

Atomic spectrometry update: review of advances in atomic spectrometry and related techniques

“…[2][3][4][5][6] A critical approach to the selection of material has been adopted, with only novel developments in instrumentation, techniques and methodology being included. It covers atomic emission, absorption, fluorescence and mass spectrometry, but excludes material on speciation and coupled techniques which is included in a separate review.…”

Inorganic Arsenic Determination in Food: A Review of Analytical Proposals and Quality Assessment Over the Last Six Years

“…Some describe food samples or summarize such aspects as pre-treatment, extraction and preservation of the arsenic species, pre-concentration, how to overcome matrix interference, and specific instrumental conditions (such as types of nebulizers, the use of a dynamic reaction cell, and internal standards). 76,77,82,88,90,91,[160][161][162] Some studies treat and discuss a specific subject in depth, as in the work of Pétursdó ttir et al 163 concerning the influence of the extraction step on the analysis of iAs in seafood, with measurement by coupled techniques. Below we summarize studies of applications of coupled techniques for iAs determination in several types of food, according to the separation technique.…”

“…Some other general reviews of element speciation provide broad information on arsenic speciation, including analytical methodology and types of food. 77,[88][89][90][91][92] Moreover, the importance of maintaining the integrity of arsenic species during the overall analytical process, with final measurement using HPLC-ICP-MS and hydride generation-atomic fluorescence spectrometry (HG-AFS), is emphasized widely in a recent review. 93 Efforts have also been made in the last decades by research scientists, government agencies (FDA and EPA), and commercial laboratories to establish methodologies for the specific determination of iAs in food products.…”

Magnetic solid phase extraction for the determination of trace antimony species in water by inductively coupled plasma mass spectrometry

“…Due to its toxicity and biological effects, antimony has been considered as a priority pollutant [1][2][3]. The permissible limit of antimony in drinking waters prescribed by the US Environmental Protection Agency (EPA) is 6 mg L À 1 [4,5].…”
