Atomic spectrometry update. Environmental analysis

Abstract

This is the twenty-forth annual review published in JAAS of the application of atomic spectrometry to the chemical analysis of environmental samples. This Update refers to papers published approximately between September 2007 and August 2008. In the analysis of air, work is focused on the need to collect and characterise ultrafines, i.e. particles below 100 nm in size, and such research is being facilitated through the development of air sampler technologies for subsequent off-line analysis of particles and aerosol mass spectrometric techniques for real-time measurements. In the analysis of water elemental speciation and development of vapour generation techniques for metalloid species continue to attach attention. Data quality and metrological issues are receiving renewed interest in part due to an increase in water quality regulations. In the field of soil and plant analysis, elemental fraction and speciation protocols based upon sequential extraction procedures, chromatographic separation procedures and synchrotron radiation x-ray techniques continue to be utilized and developed. As noted in previous Updates, laser ablation continues to go from strength to strength in being adopted as a solid sampling tool in geochemical analysis. Work continues to be focused on the production, characterization and certification of new geological reference materials.

Characterization of PM2.5 and PM10 fugitive dust source profiles in the Athabasca Oil Sands Region

“…(AAS; Varian Spectro880, Walnut Creek, CA) (Butler et al, 2009;Fernandez, 1989); (3) ammonium (NH 4 + ) by automated colorimetry (AC; Astoria 302A Colorimetry System, Astoria, OR) (Fung et al, 1979); (4) 16 carbohydrates by IC with pulse amperometric detectors (PAD) (Engling et al, 2006); (5) 9 organic acids (sum of both dissociated and non-dissociated organic forms) by IC with conductivity detector (Jaffrezo et al, 1998); and (6) WSOC by a total organic carbon analyzer (TOC, Shimadzu, Columbia, MD) (Decesari et al, 2000).…”

Selective and sensitive chemosensor for lead ions using fluorescent carbon dots prepared from chocolate by one-step hydrothermal method

“…Generally, there are many methods, which have been developed for the determination of Pb 2+ such as atomic absorption spectrometry (AAS) [10], anodic stripping voltammetry (ASV) [11], inductive coupled plasma atomic emission spectrometry (ICP-AES), and inductive coupled plasma mass spectrometry (ICP-MS) [12]. However, these methods usually require expensive and sophisticated instrumentation, time consumption and complex sample pretreatment procedures.…”

Determination trace amounts of copper, nickel, cobalt and manganese ions in water samples after simultaneous separation and preconcentration

“…Some of these sorbents may be fairly effective for preconcentration of metal ions, but their methods of preparation are lengthy and involve rigid control of conditions. Amberlite XAD resins have been also used for the preconcentration of trace metal ions from different water samples (Butler et al 2009). Amberlite XAD-4 resin is a well-known member of Amberlite XAD resins and has found widespread application for the separation and preconcentration of trace metals ions (Uzun et al 2001;Tuzen et al 2005), because it has good physical and chemical properties such as porosity, high surface area, durability and purity (Elci et al 1992).…”
