Determinação de CD, PB, e TL em água produzida por HR-CS GF AAS após extração em ponto nuvem
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM QUÍMICA, 2014-11-03)
Produced water is a major problem associated with the crude oil extraction
activity. The monitoring of the levels of metals in the waste is constant and requires the
use of sensitive analytical techniques. However, the ...
Single drop micro-extraction with O,O-diethyl dithiophosphate for the determination of lead by electrothermal atomic absorption spectrometry
(2008)
Lead was extracted as the O,O-diethyldithiophosphate (DDTP) complex from aqueous solution into a drop of CHCl3 immersed in the solution.Unlike previously reported procedures using single drop micro-extraction (SDME) for ...
