Determination of trace elements in automotive fuels by filter furnace atomic absorption spectrometry

Nickel as a Chemical Modifier for Sensitivity Enhancement and Fast Atomization Processes in Electrothermal Atomic Absorption Spectrometric Determination of Cadmium in Biological and Environmental Samples

“…The characteristic mass derived in this method represents a good value which is similar to the best values (0.4 -0.8 pg) found in the literature. 5,18,38 Something similar happens with the detection limit found in this work, which is similar to those reported in other studies using a similar technique. 18,40 We have found only one study providing a slightly lower detection limit (0.007 µg L -1 ) 29 than the presented at herein, although it was derived by using an a priori calculation, 45 different from the way recommended by IUPAC.…”

“…Thus, a two step electrothermal atomizer 4 and a filter furnace 5 have been proved to be useful for volatile elements, such as cadmium.…”

Distribution of metals in soil particle size fractions and its implication to risk assessment of playgrounds in Murcia City (Spain)

“…The fuel additive, methylcyclopentadienyl manganese tricarbonyl (or MMT), replaces tetraethyl Pb as "anti-knock" agent in gasoline; MMT enhances octane content but adds 0.2 μg Mn L − 1 gasoline (Korn et al, 2007). Contents (μg L − 1 ) of some metals in gasoline are as follows: Cd (0.13), Cr (0.4), Cu (0.9), Pb (1.5) and Ni (2.5) (Anselmi et al, 2002). Other possible sources of metals are long distance transport as well as from fertilizers applied to plants as suggested in earlier reports (e.g., Holmgrem et al, 1993;Kabata-Pendias and Pendias, 2001;Varrica et al, 2003).…”

Use of cetyltrimethylammonium bromide as surfactant for the determination of copper and chromium in gasoline emulsions by electrothermal atomic absorption spectrometry

“…The quantification of Cu and Cr in gasoline and similar products is the topic of several publications, using different sample preparation procedures and quantification techniques [3,4,[8][9][10][11][12][13]. The cationic surfactant cetyltrimethylammonium bromide (CTAB) has been widely used in several fields for a variety of applications, such as extraction procedures [14], kinetic studies [15], biotechnological and biomedical applications [16], complex reactions [17,18] and improvement of the analytical sensitivity in spectrophotometric determinations [18][19][20][21].…”
