Atomic spectrometry update – a review of advances in environmental analysis

Abstract

This review covers advances in the analysis of air, water, plants, soils and geological materials by a range of atomic spectrometric techniques including atomic emission, absorption, fluorescence and mass spectrometry.

A new synthesis scheme of pyrite and chalcopyrite reference materials for in situ iron and sulfur isotope analysis using LA-MC-ICP-MS

“…[4][5][6][7][8][9][10][11] The microanalysis of Fe and S isotope ratios can be conducted by LA-MC-ICP-MS, which provides great advantages over conventional bulk analytical techniques, [12][13][14][15][16][17][18][19][20][21] including the absence of sample preparation, efficient sample introduction, high sample throughput and the ability to distinguish the isotope variations on the scale of micrometers. [22][23][24][25][26][27][28][29][30][31] However, the accurate determination of Fe and S isotope ratios is limited by the inherent problems of LA-MC-ICP-MS, such as isotopic fractionation and matrix effect. 29,32 The isotopic fractionation in LA-MC-ICP-MS mainly appears during the laser ablation process, ionization process in plasma and ion extraction process in interface.…”

Development and Automation of a Bacterial Biosensor to the Targeting of the Pollutants Toxic Effects by Portable Raman Spectrometer

“…To meet environmental regulatory objectives, the multitude and diversity of substances to be monitored, often at trace levels, represents a major constraint. This has led to the development of a large number of specific and sensitive analytical methods, a hundred of which are European standards [1][2][3][4][5][6][7]. In addition, complementary methods to assess bioavailability and toxicity are critical for determining the true environmental impact of contaminants [8].…”

Polymer Brush-Based Thin Films via Cu(0)-Mediated Surface-Initiated Atom Transfer Radical Polymerization for Sensing Applications

“…Environmental analysis depends on spectrochemical techniques, particularly atomic spectrometry, which offers the elemental speciation and limits of detection (LODs) necessary to quantitatively describe contamination. These include mass spectrometry, absorption and emission spectrometry, X-ray fluorescence spectrometry, and infrared spectrometry . It is known that these instrumental methods are expensive, and the analysis process is laborious.…”

“…These include mass spectrometry, absorption and emission spectrometry, X-ray fluorescence spectrometry, and infrared spectrometry. 2 It is known that these instrumental methods are expensive, and the analysis process is laborious. Consequently, the environmental analysis is prolonged and remote, which may render it temporally and geographically imprecise with average errors of 26.2%, for example.…”
