“…The main operating parameters affecting chemical vapor generation and transport were varied according to a procedure based on experimental design and empirical modeling concepts. 68 Chausseau et al 69 observed that radio-frequency power and sample and nebulizer gas flow rates had great influence on time correlation between emission lines of the same element in an axially viewed ICP OES. However, the elements analysed did not present a similar behavior when those parameters where changed and a general behavior could not be established.…”

Geralmente aceita-se que espectrômetros de emissão óptica com plasma acoplado indutivamente (ICP OES) com configuração axial apresentam efeitos de matriz mais severos quando comparados aos equipamentos com configuração radial, embora gerem menores limites de detecção. Entretanto, o desenvolvimento de detectores de estado sólido associado ao arranjo óptico Littrow com rede echelle e interfaces apropriadas para remoção da zona fria do plasma vêm possibilitando a expansão do uso dessa configuração. Nesta revisão são discutidos trabalhos publicados no período de 1999 a 2006 que fazem uso da configuração axial para avaliação dos efeitos de matriz, otimização das condições de operação e análise de diversos tipos de amostras, incluindo a introdução de amostras complexas, tais como suspensões.It is generally assumed that inductively coupled plasma optical emission spectrometers (ICP OES) with axial configuration present severe matrix effects when compared to radially viewed ones, although lower detection limits are obtained. However, the development of solid state detectors associated with a Littrow optical arrangement with an echelle grating and proper interfaces for plasma tail cut off led to an increase of analytical applications based on axially viewed configuration. In this review, papers published from 1999 to 2006 using this configuration for matrix effects evaluation, optimization of the operating conditions and analysis of complex samples, such as slurries, are discussed.

“…Owing to its acute and chronic toxicity, the determination of trace amounts of tellurium has received increasing attention in recent years [5,6]. Various methods have been applied for the determination of tellurium, such as atomic absorption spectrometry (AAS) [7], atomic fluorescence spectrometry (AFS) [8], inductively coupled plasma mass spectrometry (ICP-MS) [9], inductively coupled plasma optical emission spectrometry (ICP-OES) [10] and spectrophotometry [11].…”

“…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].…”

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.
