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.

Solvent bar micro-extraction with graphite atomic absorption spectrometry for the determination of silver in ocean water

“…Numerous analytical methods have been developed in the last years to improve the determination of trace metals focused on the miniaturization and automation of the sample preparation step [10][11][12]. However, in the case of Ag innovative solutions that could overcome the drawbacks of LLE or SPE are limited to cloud point extraction [13].…”

Low-level 226Ra determination in groundwater by SF-ICP-MS: optimization of separation and pre-concentration methods

“…This method consists of the sequential application of a cation exchange resin (50W-X8) and an extraction chromatographic resin (Sr resin). The first method has been widely used to separate 226 Ra in liquid matrices (Lariviere et al 2005;Varga 2008;Cozzella et al 2011;Hou and Roos 2008;Butler et al 2015), while the latter retains Sr and partially also Ba, the main polyatomic interferences in the analysis of 226 Ra in groundwater samples (Chabaux et al 1994;Horwitz et al 1992). Due to high-precision data requirements for the development of the 226 Ra groundwater time series, the original Lariviere et al (2005) method has been modified by adding a pre-concentration part, effects of which were thoroughly investigated.…”

“…Several analytical radiometric and mass spectrometry techniques have been developed for the analysis of 226 Ra in environmental samples: radon emanation (Kim et al 2001), liquid scintillation spectrometry (Repinc and Benedik 2002), alpha-ray spectrometry (Morvan et al 2001), gamma-ray spectrometry (Johnston and Martin 1997), thermal ionization mass spectrometry (TIMS) (Cohen and O'Nions 1991), and inductively coupled plasma mass spectrometry (ICP-MS) (Chabaux et al 1994;Park et al 1999;Lariviere et al 2003;Lariviere et al 2005;Zheng and Yamada 2006;Varga 2008;Cozzella et al 2011;Hou and Roos 2008;Butler et al 2015). With the exception of ICP-MS, these methods are time consuming, often expensive, and therefore not convenient when large number of samples are to be analyzed.…”

Determination of Ultra-trace Metal Impurities in High-purity Cadmium Using Inductively Coupled Plasma Mass Spectrometry after Matrix Separation with Anion Exchange Resin

“…It is well known that there are several types of matrix separation methods, such as coprecipitation, 7 solvent extraction, extraction chromatography, and ion exchange chromatography. 8 Since the ion exchange chromatography using an anion exchange resin has some advantages against other separation methods, it was applied to separation of matrix element of Cd. In general, an anion exchange resin has high exchange capacity.…”
