“…Silver nanoparticles, prepared by the reduction of silver nitrate with sodium citrate, have been proposed as a new modifier for the elimination of interferences when determining As and Sb in seawater 144 . Pyrolysis temperatures of at least 1100 °C for As and 900 °C for Sb were achievable, reducing interferences.…”

“…163 After preparing the silver nanoparticles in-house by reducing silver nitrate with sodium citrate, the authors investigated the optimal conditions for the analysis. A particularly interesting example, by Gunduz and co-workers, described the use of silver nanoparticles as a matrix modifier during the ETAAS determination of As and Sb in sodium chloride or sodium sulfate solutions and in seawater.…”

Regarding Pd as a chemical modifier, it has been proposed that it either forms a nonvolatile intermetallic compound or a solid solution with Pd 25 or it could somehow be connected with a reaction that includes graphite material and the analyte.…”

Trace Arsenic Determination in a TiO2 Pigment Matrix Using Electrothermal Atomic Absorption Spectrometry

This work describes the use of electrothermal atomic absorption spectrometry in combination with a pyrolytic graphite-coated tube with a platform for trace arsenic (As) determination in titanium dioxide (TiO2) pigment. This type of matrix is challenging, as complete digestion in hydrofluoric acid-containing solution is needed. First, closed-vessel microwave digestion was performed for the full-sample decomposition. Next, a temperature program was optimized for drying, pyrolysis, and atomization temperatures. Furthermore, the use of a chemical modifier mixture was proposed that reduced the background contribution and prevented significant analyte loss and therefore improved the analytical procedure. The optimized method was validated for the detection (LOD) and quantification (LOQ) limits, the linear concentration range, accuracy, and precision. Special attention was devoted to the matrix-matching solutions in the calibration procedure. Linearity was confirmed in the 5.0 to 100.0 µg/L concentration range ( R2 = 0.999). The average recovery for 16 different real TiO2 pigment samples was 92.0%, and the relative standard deviation value for six replicate measurements was ≤10.4%. Moreover, the LOD and LOQ in terms of the TiO2 pigment mass was determined to be 0.2 µg/(g TiO2) and 0.7 µg/(g TiO2), respectively. The latter complies with Commission Directive 2008/128/EC, which does not allow more than 3 µg As/(g product) as the specific criteria of purity. Finally, based on scanning electron microscopy analysis of unused and several times used pyrolytic graphite-coated tubes, usage of the tube 250 times before replacement is recommended.
