The Interference Effect of a Mixture of Magnesium, Aluminium, Sulfate and Chloride on the Atomization and Vaporization of Manganese in Graphite Furnace Atomic Absorption Spectrometry

Determination of cadmium in rice by electrothermal atomic absorption spectrometry using aluminum as permanent modifier

“…15 The use of aluminum as a chemical modifier in ETAAS has been investigated by several authors. [16][17][18][19][20][21][22][23][24][25][26][27][28][29] The first paper reporting the use of aluminum as a chemical modifier in ETAAS was published by Docekalova et al; aluminum and other elements were evaluated as modifiers during the determination of selenium by ETAAS. 16 Matsusaki et al employed a mixture of nickel and aluminum nitrates, as well as EDTA tetraammonium salt, as a matrix modifier for the determination of antimony, 17 tellurium 18 and indium 19 by ETAAS.…”

“…27 Ince and Akman evaluated the performance of aluminum salts for the determination of manganese using ETAAS; the aluminum and manganese formed refractory compounds (e.g., spinel MnAl 2 O 4 ) that shifted the absorption signals of manganese to higher temperatures. 28 Recently, our research group proposed the use of aluminum as a chemical modifier for the determination of lead in sugar cane spirits by ETAAS. 29 The two-level factorial design is a chemometric tool commonly used for the optimization of analytical methods.…”

Aluminium as chemical modifier for the determination of lead in sugar cane spirits using electrothermal atomic absorption spectrometry

“…16 Several researchers have proposed using aluminium as a chemical modifier. [17][18][19][20][21][22] Docekalova et al investigated the effect of various chemical modifiers, including aluminium nitrate, on the ET-AAS analytical signal during selenium determination. 17 Tsai et al tested several chemical modifiers for copper 18 and cadmium 19 determination in nickel-based alloys by ET-AAS.…”

“…If the pyrolysis temperature was below 800 C, aluminium chloride altered the vaporisation mechanism of manganese. 22 In the present paper, aluminium was used as a chemical modifier for the determination of lead in sugar cane spirits by ET-AAS. The parameters: modifier mass, pyrolysis temperature and atomisation temperature were optimised by univariate methodology.…”
