“…A Co standard stock solution of 1 mg ml 21 was made by dissolving Co metal in nitric acid and diluting to 100 ml with 4% w/w nitric acid. A V standard stock solution (1 mg ml 21 ) was prepared by dissolving 0.2300 g of NH 4 VO 3 (Analytical Reagent, Shanghai Reagent Factory, Shanghai, China) in doubly distilled water and adjusting the volume to 100 ml. 0.2970 g of 1-phenyl-3-methyl-4-benzoyl-5-pyrazone (PMBP) (analytical reagent grade, Shanghai, China) were dissolved in 100 ml of 0.1 mol ml 21 CHCl 3 .…”

“…Esta técnica permite atomizar amostras em tubos de grafite aquecidos em torno de 3000 o C, tornando o método altamente sensível e capaz de determinar traços de um grande número de elementos, diretamente em matrizes de diversas amostras [3,4].…”

“…O tratamento da superfície de tubos de grafite ("coatings") tem sido utilizado para aumentar a sensibilidade e a vida útil do tubo em relação ao número de atomizações, mantendo boa reprodutibilidade nos resultados [3]. Desta forma, a impregnação do grafite com os elementos W, Zr, Ta, Nb e Mo, que formam carbetos estáveis e de alto ponto de fusão, altera favoravelmente as características da superfície do grafite através da competição pelos sítios ativos livres do carbono [4].…”
