Utilização da extração em fase sólida (SPE) na determinação de hidrocarbonetos ...
Cavalcante, Rivelino M.; M. Filho, Nilton S.; Viana, Rommel B.; Oliveira, Isadora R. N.; Nascimento, Ronaldo F.; Silveira, Edilberto R.Polycyclic aromatic hydrocarbons (PAHs) are a great environmental concern mainly because of their toxic, mutagenic and carcinogenic potential. This paper reports utilization of the solid-phase extraction (SPE) technique to determine PAHs in environmental aqueous matrices. The recovery from environmental aqueous matrices fortified with PAHs varied from 63.7 to 93.1% for atmospheric liquid precipitation, from 38....
