“…The calibration solution and the sodium tetrahydroborate solution were fed at flow rates of 2 ml min' and of 0.8 ml min 1, respectively, to the same apparatus as decribed earlier. 16 Linear calibration curves were achieved up to 4 ng mi-' of arsenic(V) and 8 ng ml-' of selenium(IV). Sample dissolution.…”

“…Then the determination was completed as described earlier. 16 Determination of arsenic in nickel powder. After the effluent was concentrated as described above, the contents were transferred to a 25-m1 volumetric flask with 4 ml of 6 M hydrochloric acid including 1 ml of the 1,10-phenanthroline solution and diluted to the mark with water.…”

“…No gerador de coleta, o vapor pode ser coletado em tubo fechado, sob pressão (coleta por pressão) 15,[26][27][28][29] ou em tubo U imerso em nitrogênio líquido (coleta com armadilha a frio). Nele, os hidretos são capturados 24 , mas não [30][31] .…”

“…The importance of this type of data is well established and this type of analysis is well established and has been been used for decades . Various wet digestion procedures have .been used for the determination of hydride forming elements and have been amply described in the literature (Thompson and Thomerson, 1974;Aslin, 1976;Chapman and Dale, 1979;Johnson and Maxwell, 1981;Crock and Lichte, 1982;and Narasaki and Ikeda, 1984). The application of atomic absorption coupled with hydride generation as a means of analysis has also been amply described in the above references .…”
