Antimony and chromium determination in Brazilian sugar cane spirit, cachaça, by electrothermal atomic absorption spectrometry using matrix matching calibration and ruthenium as permanent modifier

Feasibility of internal standardization in the direct and simultaneous determination of As, Cu and Pb in sugar-cane spirits by graphite furnace atomic absorption spectrometry

“…Only one samples presented a Cu and Pb content higher than 5000 g L −1 and 200 g L −1 , respectively, the maximum established by the Brazilian Ministry of Agriculture, Livestock and Food Supply [6]. The levels of As, Cu, and Pb found in this work were close to those obtained for cachaç a reported in the literature [11][12][13][14]. Table 2 Results (n = 4) for As, Cu and Pb determination in Brazilian sugar-cane spirits by GFAAS using internal standardization and by ICP-MS as a comparative technique.…”

“…GFAAS was employed as technique for determination of Cr, Sb [10], Al, Cd, Pb [11], Al, As, Fe, Mn, Ni [12], and As, Cu, Pb [13,14] in cachaç a. These methods circumvented matrix effects by employing matrix matching as the calibration method.…”

“…These methods circumvented matrix effects by employing matrix matching as the calibration method. Among medium used are 40% (v/v) ethanol [10,11], 10% (v/v) ethanol + 5 mg L −1 Ca, Mg, Na, [13] and cachaç a sample [12,14]. Internal standardization (IS) can also be adopted as a simple and efficient strategy to avoid matrix effects in GFAAS [15][16][17][18][19][20][21].…”

Advances in assessing the elemental composition of distilled spirits using atomic spectrometry

“…Graphite tubes without platforms are rarely used [18,31,45]. GF-AAS is applied to determine a specific group of trace elements {i.e., Al [17,19,34,46], As [1,6,19,37], Cd [11,17,19,20,38,45,46,49,50], Cr [11,18,31,45], Cu [1,6,9,37,50], Fe [52], Ni [9,11,31,45], Pb [1,4,6,9,14,16,17,19,33,37,46,[49][50][51] and Sb [18]}.…”

Elemental and isotopic characterization of cane and beet sugars

“…There are also several reports on trace element contents in sweets and other sugar-based products (Canuto et al, 2003;Naqvi et al, 2004). Studies on the transfer of chemical contaminants through the food chain can provide useful information for the development of surveillance programs aimed at ensuring the safety of the food supply and minimizing human exposure to toxic agents (Bayat et al, 1995;Biego et al, 1998;Dolan and Capar, 2002;Lombardi-Boccia et al, 2003).…”
