“…3 presenting background corrected net intensities in reference to the highest value in the measurement series) that relative background corrected net intensities of As and Hg atomic emission lines increased with concentrations of THB and HCl despite the fact that the volumetrically measured amount of hydrogen increased from 0.7 ml min À1 (at 0.1% THB) to 13 ml min À1 (at 1.0% THB). In accordance with what was previously described, 8,9,16,37,38 it seems that the increasing amount of hydrogen may affect excitation conditions in the Ar-MIP and deteriorate the response for As and Hg. This effect can be compensated to a degree by higher efficiencies of the AsH 3 and Hg 0 generation at higher THB concentrations used for the CVG reaction.…”

Spectroscopic and analytical characteristics of a low power atmospheric pressure mixed argon-helium microwave induced plasma were examined for its usefulness in the determination of As, Sb and Hg by optical emission spectrometry and using a continuous flow chemical vapor generation of these elements (AsH 3 , SbH 3 , Hg 0 ) in the reaction with sodium tetrahydroborate. The effect of the concentration of helium in the plasma gas on excitation, vibrational and rotational temperatures and the electron number density in the discharge obtained from argon and mixtures of argon with helium was studied to evaluate changes in excitation conditions and their impact on the analytical performance of the plasma. It was found that the presence of 10-20% v/v of helium in the carrier/plasma gas is very convenient for the excitation of As, Sb and Hg introduced to the plasma via the volatile species generation reaction. In reference to limits of detection of 4.1 (As), 1.8 (Sb) and 1.4 (Hg) ng ml À1 , such a plasma has a considerably better analytical performance as compared to the plasma generated only in an argon atmosphere.

“…During the last decades, hydride generation atomic spectrometry has become the most used technique for the determination of trace amount of elements that generate volatile species [16][17][18][19][20][21]. Hydride generation inductively coupled plasma atomic emission spectrometer is a sensitive tool for the determination of elements such as As, Bi, Sb, and Sn [22,23].…”

“…This enables reducing or even eliminating interference and increasing the sensitivity at the same time. However, different kinds of interferences are present, such as chemical and spectral interference [16,22,23]. Chemical interferences can be commonly separated to those in liquid phase and gas phase; for example, transition metals can cause chemical interferences in the liquid phase.…”

Hydride generation inductively coupled plasma optical emission spectrometry (HG-ICP-OES) was used in the determination of As and Sb concentrations in fly ash samples. The effect of sample pre-treatment reagents and measurement parameters used for hydride generation was evaluated. Due to memory effects observed, the appropriate read delay time was adjusted to 60s resulting in RSDs 0.6% and 2.3% for As and Sb, respectively. The most suitable volumes of pre-reduction reagents for 10 mL of sample were 4 mL of KI/ascorbic acid (5%) and 6 mL of HCl (conc.). The determination of Sb was significantly interfered by HF, but the interference could be eliminated by adding 2 mL of saturated boric acid and heating the samples to 60°C at least 45 min. The accuracy of the method was studied by analyses of SRM 1633b and two fly ash samples with the recovery test of added As and Sb. As high a recovery as 96% for SRM 1633b was reached for As using 193.696 nm with two-step ultrasound-assisted digestion. A recovery rate of 103% was obtained for Sb using 217.582 nm and the pre-reduction method with the addition of 2 mL of saturated boric acid and heating. The quantification limits for the determination of As and Sb in the fly ash samples using two-step ultrasound-assisted digestion followed with HG-ICP-OES were 0.89 and 1.37 mg kg(-1), respectively.
