Simultaneous Determination of Metals and Sulfur in Crude Oil Distillation Residues by Icp-Oes

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.…”
