The secondary line at 338.289 nm was used for all measurements. A manual solid sampling accessory and solid sampling platforms were used for sample introduction. A mass of 400 μg of ruthenium was thermally deposited on the platform surface as permanent modifier. The optimum pyrolysis and atomization temperature was 1,000 and 2,000 °C, respectively. Aqueous standard solutions were used for calibration exclusively. The analytical parameters obtained for the proposed method were as follows: characteristic mass, 4.4 pg Ag; detection limit (3σ, n = 10), 17 ng g− 1; and quantification limit (10σ, n = 10), 58 ng g− 1. These limits are equivalent to 0.05 and 0.16 ng m− 3, respectively, for 0.36 mg of sample mass (filter + APM) and an average volume of 1,440 m3 air that had passed through the filter. The certified reference material urban particulate matter, NIST 1648, was used for checking the accuracy. Four filter samples with APM collected in Buenos Aires, Argentina, were analyzed. According to our study, the concentration of silver (average ± confidence interval at 95% level, n = 5) varied between 0.64 ± 0.06 and 1.18 ± 0.07 μg g− 1, corresponding to 1.99 ± 0.11 and 4.54 ± 0.26 ng m− 3. The precision, expressed as relative standard deviation, varied between 1.6 and 7.1% (n = 5). The analytical method proved to be simple, fast and reliable. Highlights ► Determination of Ag in APM sample by HR-CS SS-GFAAS was proposed. ► The proposed method is simple, fast, reliable and suitable for routine applications. ► Procedure of determination of silver in environmental samples avoiding dissolution. ► Solid sampling is environmentally friendly when compared conventional methods.Submitted by Santiago Fabio (fabio.ssantiago@hotmail.com) on 2013-10-29T19:46:35Z No. of bitstreams: 1 5555555.pdf: 374813 bytes, checksum: 9e24884b818f84498479904799d6df24 (MD5)Made available in DSpace on 2013-10-29T19:46:35Z (GMT).
