Abstract:, VR) using microwave-induced combustion (MIC) was developed for simultaneous determination of metals (Ba, Co, Fe, Mg, Mn, Ni and V) and sulfur by inductively coupled plasma optical emission spectrometry (ICP-OES). Samples were wrapped in polyethylene films and combusted using 20 bar of oxygen. Nitric acid solutions were evaluated using 5 min of reflux after combustion. Accuracy was evaluated using certified reference material and comparison with the results obtained by microwave-assisted wet digestion (MAWD)… Show more
“…The data for Ni and V in AR and VR are on the same order as those provided elsewhere. 40 Druzian et al, 49 used a method based on the sample treatment by microwave combustion and ICP-OES elemental analysis of petroleum distillation residues. These authors found that the iron concentration was higher in AR than in the VR.…”
The present work describes and discusses the use of a high temperature sample introduction system, hTISIS, for the analysis of crude oil and heavy petroleum fractions by means of inductively coupled plasma optical emission spectrometry, ICP-OES.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
