Trace element determination in sediments: a comparative study between neutron activation analysis (NAA) and inductively coupled plasma-mass spectrometry (ICP-MS)

“…In the last two decades of the twentieth century, the potential for inferring sediment provenance increased dramatically as the results obtained from routine mineral analyses (using a microscope and XRD) began to be combined with information about mineral magnetic parameters, trace element and isotope concentrations, and geochronological data obtained by using an expanded range of analytical techniques that include, for example, Instrumental Neutron Activation Analysis, Inductively Coupled Plasma Mass Spectrometry and Accelerator Mass Spectrometry (Marqués et al. 2000; Tuniz 2001).…”

This article is concerned with the changes that erosion and transport have on the properties of sediment as it moves through a dispersal system, which point to the processes responsible for its dispersal, and the ways in which the characteristics imparted to sediment in the source area by parent lithology and climate can be used to indicate its spatial origin (provenance). Examples are provided of the changes to particle size and shape that have been observed to occur during transport by water, wind and ice, and of the different approaches used to ascribe provenance that rely on conservative physical and chemical properties. These include mineral, stable and radioactive isotope, major and trace element compositions and environmental magnetism. The different uses to which such data have been put and the range of scales at which provenance studies have been conducted are illustrated using examples drawn from investigations conducted in marine, fluvial and lacustrine settings.

“…There are numerous techniques applicable for Bi determination, but most of them have some limitations, especially for the analysis of solid environmental samples. Inductively coupled plasma mass spectrometry (ICP MS), inductively coupled plasma optical emission spectrometry (ICP OES) (Hasssanien and Ali 2012 ; Ivanova et al 2001 ; Aulinger et al 2002 ; Marques et al 2000 ; Krishna and Arunachalam 2004 ; Gundersen et al 2000 ) and the techniques based on the atomic absorption (Ivanova et al 1997 ; Sengupta and Bouvier 1995 ; Moscoso-Perez et al 2003 ; Kula et al 2009 ) are the most often used for Bi determination. If the multi-elemental analysis is not necessary, the atomic absorption spectrometry (AAS) can be considered the method of choice (Das et al 2006 ).…”

Slurry sampling graphite furnace atomic absorption spectrometry technique was applied for the determination of Bi in environmental samples. The study focused on the effect of Zr, Ti, Nb and W carbides, as permanent modifiers, on the Bi signal. Because of its highest thermal and chemical stability and ability to substantially increase Bi signal, NbC was chosen as the most effective modifier. The temperature programme applied for Bi determination was optimized based on the pyrolysis and atomization curves obtained for slurries prepared from certified reference materials (CRMs) of the soil and sediments. To overcome interferences caused by sulfur compounds, Ba(NO3)2 was used as a chemical modifier. Calibration was performed using the aqueous standard solutions. The analysis of the CRMs confirmed the reliability of the proposed analytical method. The characteristic mass for Bi was determined to be 16 pg with the detection limit of 50 ng/g for the optimized procedure at the 5 % (w/v) slurry concentration.
