Sample treatment was based on quantitative leaching of mercury species from fish tissue with ultrasound-assisted acid-toluene extraction. The extracted mercury species analyzed with GC-MIP-OES attained detection limits of 5 and 9 pg for methylmercury (MeHg) and ethylmercury (EtHg), respectively. A complete chromatogram could be completed in 1.5 min. MeHg values obtained with GC-MIP-OES were matched with organic mercury values obtained with selective reduction cold vapour- atomic absorption spectrometry (CV-AAS). 2008 artículo científico 1856-5301 https://www.redalyc.org/articulo.oa?id=93330204 en http://www.redalyc.org/revista.oa?id=933 Avances en Química application/pdf Universidad de los Andes Avances en Química (República Bolivariana de Venezuela) Num.2 Vol.3 |
