O primeiro é baseado na preparação de uma microemulsão da amostra que é diretamente injetada no tubo de grafite. As temperaturas de pirólise e atomização, 1500 e 2700 ºC, respectivamente, foram otimizadas a partir das curvas de temperatura. Para este procedimento obteve-se um limite de detecção de 0,10 mg g-1 e uma massa característica de 87 pg. O outro método utiliza digestão da amostra com ácido sulfúrico, ácido nítrico e peróxido de hidrogênio. As temperaturas de pirólise e atomização, otimizadas, foram 1000 e 2700 ºC, respectivamente. Para este procedimento, obteve-se um limite de detecção de 0,25 µg g-1 e uma massa característica de 63 pg. A exatidão de ambos os métodos foi confirmada pela análise do material de referência certificado NIST SRM 1634c-trace metals in fuel oil.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2011-12-22T10:26:49Z No. of bitstreams: 1 a18v18n8.pdf: 176718 bytes, checksum: 506d203f43553b90930636a47de48cf1 (MD5)Made available in DSpace on 2011-12-22T10:26:49Z (GMT).
